How to Troubleshoot a Siemens Speedstream 4200 Modem

Any Internet service provider (ISP) will have its own technical support experts, but it is often wise to know some basic troubleshooting steps so you can address simple problems on your own rather than spending time on the phone with a technical support rep. If you use the Siemens Speedstream 4200 DSL modem, follow some simple steps to troubleshoot problems you may come across.Instructions


Things You'll Need:

  

  1.Reset the modem by unplugging its power cord, waiting a full 30 seconds and plugging it back in. This is a useful troubleshooting step if the modem will not go online or the connection drops intermittently. Allow the modem to run through its entire boot cycle and test the connectivity again.

   2.Unplug the Ethernet cable that attaches the Speedstream to any router or other home networking device you may use and plug it directly into the computer's Ethernet port. This is known as "bypassing" the router, and is also a useful way of troubleshooting no connectivity, slow speeds or intermittent connectivity. After bypassing, reset the modem as in Step 1 and test your connection again.

   3.Reconfigure the modem by opening an Internet browser with an Ethernet cable still attached from the modem to the computer, typing "10.0.0.1" into the address bar and pressing the "Enter" key. You can find information on configuration settings in the Speedstream 4200's manual (see Resources), but you will likely need to contact your ISP's technical support department to gather connection information specific to your Internet service. If your modem is incorrectly configured for your Internet service it will never go online, so reconfiguring the modem can resolve a lack of connectivity.

Clearwire throttling at-home WiMAX users?

Ah, throttling. Can't ever seem to fully shake it, can we? Just weeks after hearing about a similar issue with the EVO 4G, scores of Clear at-home WiMAX users are now up in arms over apparent throttling on certain accounts. As the story goes, it seems as if the company is pulling back on upload and download speeds (from 10Mbps to around 0.25Mbps) for users who have consumed between 7GB and 10GB in a month, which is comically low even compared to Comcast's hated 250GB / month usage cap. Forum users are finding customer service lines to be no help whatsoever, and some digging has found that this may all be a part of a network traffic administration program that's ongoing within Clearwire. Have any of you seen similar issues? How much data are you sucking down per month? Does your usage clock still show up in your account profile? Let us know in comments below.

Mobile devices push portable wireless modem sector

ABI Research's "Cellular Modem Product Tracker" indicates that hundreds of wireless modem models are now available to consumers. Manufacturers are racing to produce more portable wireless modems amid the continuing growth in the demand for mobile broadband access.
ABI Research principal analyst Jeff Orr said that with the number of mobile broadband subscribers expected to exceed 150 crore by 2015 and with consumers buying more Internet-enabled wireless devices such as Ipads, netbooks and smart phones, "cellular modems used to connect Internet services to mobile devices are, therefore, gaining in popularity."
While most support GSM, GPRS, EDGE or HSDPA network technologies, a growing number use 4G technologies. They also support various frequency bands and access technology and come is all sorts of form factors such as PC cards, USB dongles, internal Mini-Cards and mobile hotspot routers.
One such device is Huawei's E583C portable hotspot, which provide 7.2Mb/s downloads and 5.76Mb/s uploads. Weighing just 90g, it can provide an Internet connection to up to five Wi-Fi-enabled devices at a time. Some products provide 21.1Mb/s downloads using HSPA+ connections.
Some of the new wireless modems that debuted this year are Sierra Wireless' Aircard 250U and Franklin Wireless' U600. They both support 4G connections using mobile WiMAX. WiMAX modems for PCs are also available from Green Packet, Intel and Motorola. On the LTE front, vendors are preparing to sell new products, such as Huawei's E398 USB modem, which supports LTE, UMTS and GSM.

Franklin launches U600 3G and 4G USB mobile broadband modem through Sprint

Franklin Wireless, a provider of wireless data products, has announced the availability of its new U600 3G and 4G USB mobile broadband modem through Sprint.
Franklin Wireless's new U600 modem includes many features including a 270-degree rotating hinge, four external antenna ports, firmware update management object and global positioning system location based services while on 3G and 4G antenna TX diversity which optimizes uploads while on WiMAX.
The U600 3G and 4G USB modem supports Windows 7, Windows Vista, Windows XP and Mac OS 10.5, 10.6 with Intel. In addition, it has separate light-emitting diode displays that make it easy for users to know whether they are connected to Sprint's 3G or 4G network, the company said.
OC Kim, president of Franklin Wireless, said: "We are delighted to announce our continued partnership with Sprint and look forward to providing its customers with our newest 3G and 4G USB mobile broadband modem. The U600 builds upon the great successes Franklin Wireless has enjoyed with earlier 3G and 4G USB modems and we are very pleased to be able to continue to support Sprint as it builds its mobile broadband user base through the rapid deployment of its 4G network."

Modem used in an alarm system

This alarm system senses motion and then alerts you by phone. [Oscar] had an old external modem sitting around and, with some wise hardware choices, he came up with a simple circuit to use it. First up is the PIC 16F628A chosen because it doesn’t require an external crystal. This connects with the modem via a DS275 RS232 transceiver because it requires no external parts for connection. The final portion of the puzzle is a PIR sensor that triggers a pin interrupt in the sleeping PIC, which then dials your number to alert you. It doesn’t look like anything happens other than your phone ringing, but that’s enough for a simple system. We’re just happy to see how easy it was to use that modem… time to go hunting for one in dreaded junk trunk. Don’t miss the clip after the break.

Nokia sells wireless modem business to Renesas in bid to refocus

Nokia just announced a $200M-ish deal to sell its wireless modem business to Japan's Renesas Electronics Corporation. The deal is part of a broader alliance to develop HSPA+ and LTE modem technologies while working together to research future radio technologies. Per the agreement, Nokia will transfer its wireless modem technologies for LTE, HSPA and GSM standards, "certain" related patents (interesting in light of the Apple lawsuits), and about 1,100 Nokia R&D staff to Renesas, the majority of whom are located in Finland, India, the UK, and Denmark -- assuming regulatory approval of course, something the two expect to receive by the end of the year. Why now? Well, according to Kai Oistamo, Executive Vice President at Nokia, "The alliance enables us to continue to focus on our own core businesses, connecting people to what matters to them with our mobile products and solutions." Sounds like somebody's slimming down in preparation for a fight.

P.S. Though the 'Shop above only shows a Nokia USB modem, the agreement goes much deeper to cover the modem technologies used inside billions of Nokia handsets. So yeah, this is a fairly significant change of direction for Nokia.

Intel buys cellular chip maker Comsys

Intel seems to have taken yet another surreptitious step towards the world of cellular, snapping up bankrupt Israeli based Comsys Mobile Communication and Signal Processing, a WiMAX/GSM modem chip maker for a reported $30 million.
 The acquisition, said to have taken place in late May, has not been confirmed by Intel, but has been widely reported in the Israeli press, as well as by Forward Concepts analyst Will Strauss who claims his comsysmobile.com email addresses now work with intel.com.
Comsys started out as a modem making firm for PCs developed for Conexant Systems, but later developed IPR for 2G and 2.5G cellphone modems. Strauss notes that the firm’s biggest licensee was Texas Instruments, which later purchased the Comsys cellphone operation.  Comsys, says Strauss, then changed direction and entered the WiMAX business, Intel’s playing field, with its combo WiMAX/GSM modem chip.
Strauss says Comsys’ 80 employees will now join Intel’s major wireless R&D centers in Haifa and Petah Tikva.
Another source close to both firms confirmed to RCR Unplugged, “Comsys did, or was about to, go out of business, so Intel just hired some of their employees.”
The source goes on to say he doesn’t think Intel acquired any Comsys products, but that it was normal and expected that Intel “continue to hire wireless expertise inside Intel…not just for Wifi or WiMax, but many areas.”
Meanwhile Strauss notes that “although 3G capability was mentioned in the Israeli news reports of the acquisition, we are unaware of such IPR by Comsys.”
He added, “Comsys has closed shop, and I suspect that Intel wanted their brains and IPR, not their chips.
“Any cellphone chips that Intel may make, whether 3G or 4G will have to also “down-clutch” to 2G and Comsys has that IP,” Strauss told RCR Unplugged.
Strauss posits that Intel is “anxious” to return to the cellular business, realizing it is the only segment that can rival the PC space. “Intel, now under different management, is searching for ways to get back into the cellphone chip market that it once abandoned,” he claims.
The firm, says Strauss, had reasonable success with its XScale-based application processors, but had a tough time merging its multi-level flash memory on the same die with its baseband “Frio” DSP core. Intel sold both properties to Marvell, which has since revitalized and expanded on them.
Intel has been making massive efforts to scale its Atom chips enough in terms of size and power usage to make them suitable for cell phones. Several months back the tech giant announced its latest iteration of Atom, the Atom Z6xx based on the latest “Moorestown” silicon had cut idle power to 1/50th of its predecessors and that power consumption for audio processing had reached 1/20th of the previous version. Not a bad start.
This achievement, admitted Intel, was largely thanks to the company’s use of Freescale’s power management IC (PMIC) and Strauss claims an audio DSP in Intel’s accompanying Platform Controller Hub MP20DSP also went a long way to slashing most of the audio processing.
Still, rumors abounded that Intel was on the prowl for a cellular chip company, with Infineon Technologies AG topping most speculators’ lists. Such an acquisition would, in Strauss’ opinion, have put Intel head-to-head with Qualcomm, the world’s largest fabless chip house and #1 cellular chip vendor.
Unfortunately for Intel, however, Infineon was not up for sale, so the chip giant went looking elsewhere, and appears to have found at least some of what it was looking for.
As to why Intel hasn’t formally announced this ‘acquisition,’ Strauss told RCR “Intel doesn’t have to inform the public unless there’s a ‘material effect’ on its revenues or profits.”

Comcast TV, modem prices set to increase Aug. 1

Comcast cable TV prices will increase Aug. 1, rising to an average monthly cost of $3.21 or nearly 5 percent for its customers in Western Washington and Spokane, the company announced today.Internet modem prices also will increase $2 and those customers who subscribe only to Comcast's high-speed Internet service will see a price increase of about $3, spokesman Walter Neary said.
Comcast prices for its "limited basic" cable TV service remain unchanged, and subscribers to its "Digital Economy" package will see a decrease between four cents and $10.04.
Increased business expenses and offering customers more services resulted in the price increases, Neary said. Comcast has about 1.1 million customers in Western Washington and Spokane.

Makes the BlackBerry as a modem for the iPad

Apart from the existence of pro and cons about iPad presence, it seems the latest tablet device from Apple has brought new waves around the world, not only those users who feel eiphoeria with this iPad presence, even some computer manufacturers have chimed in to make a similar device.
And the most exciting thing for us is, that the BlackBerry device was very friendly with the iPad, so we can make the BlackBerry as a modem (tethering modem) to access the Internet using the iPad. By using the WiFi feature also owned a BlackBerry and iPad apparently this can be done, and this method becomes warm conversation at one of the leading BlackBerry forums.
To do this, we are required to download an application called iBluever cydia and install it on iPad device and install the application on the BlackBerry, called PDANet (maybe we are not unfamiliar with the last application, yaahh, it was never used on Palm devices, long before the BlackBerry comes … oops).

After all applications were installed on each device so we can activate the WiFi on the iPad. For the record, we must have access to Internet data packets using Internet access using a BlackBerry, because it makes data access a BlackBerry with a BlackBerry device as a modem does not enter into the unlimited data package (yes, I know most readers know this Twitteling .. ). For more details, we observe there are good references are the steps to do it through a forum that I meant earlier.

Good news for those iPod Touch users, that the tricks above can also be used for the iPod touch device and not just for the iPad. although the connection is not as fast as 3G connectivity but is more than enough to connect the iPad or iPod Touch with the virtual world while it is far from a WiFi connection.

Use Your Android Phone as a Wireless Modem

You know you can surf the Net on your Android phone--but did you know that the same phone can also enable you to surf the Net from your PC?

We're talking about something called tethering. In a nutshell, tethering allows you to use your smartphone like a wireless modem: You connect it to your computer, then use its 3G connection to get online.

Carrier Considerations

Before you start thinking about tethering with your Android device, you should check with your carrier to learn about its policies and conditions. Some carriers offer their own fee-based tethering services for certain phones; others forbid the practice altogether or assess penalties if they discover you're d

As long as your carrier doesn't object, the only other consideration is data usage. While tethering, you'll be harnessing your phone's 3G connection to use the Internet from a computer, so you will be consuming a potentially sizable chunk of data. If your smartphone plan includes unlimited data, you should be fine; but if your plan allows only a certain amount of data per month, be sure to keep that restriction in mind.

First Steps to Tethering

Carrier-provided options aside, there are numerous ways to tether your phone to your laptop or desktop PC. Many of them require tinkering with advanced configurations on your Android device; we won't be getting into those here. The option we'll be explaining involves little more than installing a couple of programs and clicking on a couple of basic settings.

Let's begin with your mobile phone: Open up the Android Market and search for an app called PdaNet. Download and install it to your phone (it's currently available free of charge).

Once the app is installed, you'll need to download the companion program to your PC. Click over to June Fabrics (that's the name), and select the edition that's right for you. As of this writing, the program supports 32-bit versions of Windows XP, Windows Vista, and Windows 7; 64-bit versions of Windows Vista and Windows 7; and versions 10.5 and 10.6 of Mac OS.

Before you move on to the next step, you need to adjust one setting on your Android phone. From the home screen, tap the Menu key and select Settings. From there, select Applications, and then Development. Now check the box that says USB debugging. When the confirmation dialog box appears, press OK.

This setting allows the PdaNet app to stream data directly from your phone to your PC. It is a setting frequently used by developers. In theory, however, as the confirmation box explains, it could be used maliciously. For your protection, you should go back into this menu and disable the USB debugging setting whenever you are not actively using the tethering function.

Starting Your Connection

Take a deep breath--you're almost done. Plug your Android phone into an open USB port on your PC. Run the PdaNet app on your phone and select the Enable USB Tether option. The app will confirm that you've downloaded and installed its PC-based cousin; click Already installed to continue.

After verifying the connection, the app will tell you that it's on and running as a background service on your phone. Now, go to your PC and look for the PdaNet icon in your system tray--it's a rectangular box that looks like a cell phone. Right-click the icon and select Connect from the pop-up menu that appears.

At this point, everything should be all set (woo-hoo!). The PdaNet PC program should pop up a confirmation that you're connected, and a notification should appear on your desktop informing you that the PdaNet modem is up and running. Your computer is now online through your phone's data connection; you can open a Web page, check e-mail, and do practically anything else you could normally do while connected to the Net.

One final note: You may have noticed that the PdaNet Android app has a second option on its main screen: Enable Bluetooth DUN. If you're using a computer that has Bluetooth functionality, you can connect your phone to your PC wirelessly using this option instead of the Enable USB Tether option discussed above.

Simple setup to prepare your own radio modem

Eric Seifert worked on the idea of using an “iPod” FM Transmitter and a standard radio receiver with a headphone jack to create a radio modem. The results were positive. Therefore, he put this information open for anyone who enjoys DIYs. Some examples encoding and decoding software are available on his site to help you.

First requirement, a Linux box with the ALSA and SDL libraries. He used a standard PC sound card, an iPod FM transmitter, and an FM radio to construct a radio modem at home. FM transmitter is linked to the sound card that outputs amplitude encoded data. The FM radio receiver takes care of the transmission and transfers it to soundcard’s line-in for further decoding.

You need not worry about the complexity of the procedure as the hardware set up is simpler than it appears. Don’t miss this opportunity to acquaint yourself with more circuits while having fun in your spare time.

Beceem's BCS500 4G modem splices WiMAX and LTE into one chip, sampling later this year

When we were told market research pointed to WiMAX and LTE standards for 4G connectivity coexisting, we didn't expect they'd do it quite so closely. Beceem, the maker of the WiMAX chips inside "every device in Clearwire's network," is working on a 4G modem that can handle both WiMAX and LTE, with the added extra of being able to move seamlessly between the two networks in order to find the best signal possible. The mashup of the two standards makes sense in light of all the equivocation from Clearwire and Sprint on the subject of which one they'd prefer, and would be a more than welcome simplification of our collective 4G future. Anyhow, the latest development is that Beceem and Motorola are working to pair the BCS500 to the latter's WiMAX 4G infrastructure, with the first dual-mode chips set to start sampling "later this year" and hit mass production in early 2011.
