CAUTION - this will reset ALL ROUTER SETTINGS. In other words, you will lose the configuration information and will need to reconfigure all of your settings. .

  3. Press and hold the button until the power light flashes red/green.
  4. Release the button.
  5. Now go through the setup instructions found in the manual.

Speedstream 5260 (5262) //EnterNet300

i m sorry to say that enternet300 1.5c is not available these days in online.

instead of enternet , windows xp has a similar built in interface, its 99% similar to enternet

try configurin your isp using this simple procedure, configuring this interface is pretty easy compared to enternet.

so go ahead and give a try . i m sure u wont regret !

•Go to Start->Control Panel •Then Network & Internet Connections
•Then Network Connections
•Select Create a new Connection
•Click Next
•Select Connect to the Internet then click Next
•Select Set up my connection manually then click Next
•Select Connect using a broadband connection that requires a user name and password then click Next
•Type in your ISP's name then click Next (**See Note Below)
•Enter your user name as provided by your ISP. 

for example: You might need to inlude your domain as part of your username.

•Enter your password, then confirm it

•Select Use this account name 
•Select Make this the default Internet connection then click Next
•Select Add a shortcut to this connection to your desktop then click Next
•Hit Connect

i guess this must resolve your issue :)

Belkin Router - Network works for 5 minutes than everything loses internet capability.


           This issue usally occurs when the router is able to save the data stored or in  other words the Router id not able to AUTHENTICATE,  but as you already got a new router and you have already done the fireware upgradation of the router. we can also upgrade the firmware of your speedstream modem.


plz do these following steps ,( plz disconect the router from the computer and modem completly while doing the steps )




The Efficient 5260 modems that can be upgraded are as follows:

Look on the label on the bottom of your modem. It should read:

SpeedStream 5260 Ethernet ADSL Modem
Part Number: 060-5660-00x (where x=any number)
Revision: any (all revisions seem to work)

If your part number reads anything else, your modem is most likely not upgradable.

For those curious, 5660 models 003 and earlier do NOT support G.Lite ADSL, only DMT. If you are buying a 5260 or 5660 model secondhand, and your DSL ISP uses G.Lite DSL, it would be a good idea to check with the person selling you the DSL modem.

UPDATE: As of 5660 Firmware v2.3.0(2) and later all 5660 including 5260/5660 hybrids support G.Lite ADSL. It pays to use the latest Firmware.

Can't get modem to work

speedstream 5260 modems don't have a built-in pppoe in it, so with your win xp OS you just have to make a broadband connection using the new connection wizard by either going to control panel > network connection > new connection wizard or in internet explorer, click on tools menu > internet options > connection tab > click on setup button. follow the wizard and type your username & password on your registered internet account. also make sure you delete your previous broadband connections (if you have set up one before) to avoid conflict with the new connection.
the set up is different if you are using lower versions of windows OS, (like win2000, ME, 98 SE/ FE or 95? ) or Mac 9 you may need to install a pppoe software such as Enternet 300, WinPoet, etc.

Not working ,just red light

If you have all red lights, this indicates a problem with the router. Please contact your ISP to make sure that your internet connection is working correctly. Did you receive this router from your ISP or did you purchase it directly? Has it worked in the past and just suddenly stopped working? Please provide more details for me to provide you with further options.
