    Hello,
    I have a Lynksys WRP400 that diconnect me from the internet after 1 to 2 hours internet browsing. I have updated the firmware, but it doesnt help. The only action that helps is diconnecting the power cord for a minute, then plug it in again.
    Sometimes it is so bad that I only have a connection for about 10 minutes, other times I can surf 2-3 hours before the error occures...
    I have the following Internet configuration:
    Computer - Lynksys WRP400 - Siemens modem.
    Thanks in advance for anyone who can help me with this problem, it is really annoying!:mad:

    I assume you have a DSL connection (Siemens modem). When you get disconnected, are you getting disconnected from the Internet or disconnected from the router?

    If lose connection to the router then the problem is caused by the router or something on the computer. If get disconnected from the Internet then the problem could be a failing router or the ISP.

    DSL settings in the router will have a "lease time" setting, and there may also be a router setting for "disconnect when idle or always ON. "

    Is your phone service also routed via the Linksys? If so, does phone cut off too? If so, the problem is likely the modem.

    To verify which device is failing, you'd have to connect the modem directly to a comp and see if Internet connection remains constant. This t-shooting action requires all that the comp & modem be underpowered, cables connected and then power ON modem, then power ON computer. To revert back to router you must also power OFF all devices, then then ON all devices in sequence: modem - router - comp.

    If you are sharing the DSL with a phone line, make sure appropriate line filters are installed. Where the modem connects to the wall jack there should be a 2 port filter. Make sure the modem is plugged into the correct port on the filter. Also, make sure every phone jack in the house that has a phone attached to it, has a single port filter installed.

    Next, I believe this is a wireless router you are using. If you have a wireless telephone within 4' of the router, move it. The router is most likely 2.4Ghz and if the phone is also 2.4Ghz. You will have the problems you have described. If there are any other wireless devices that are near the router move them also.


    Now if you are using a Voip Telephone line (such as Vonage) this presents another problem, let me know if that is the case.

    Hope this helps

    Sorry, I was not clear enough about the issue. The problem is the router itself. When it disconnects, I cant even communicate with the router. I dont use a VOIP phone at all.

    I hesitated to jump in here since I'm definitely not a hardware expert but I have experienced two Linksys routers with the exact symptoms you describe.

    After trying everything I could think of and everything the experts recommended, they were both "fixed" by replacing them.

    I took one of them home to work on and got the same results (connects after power cycling, randomly disconnects) with known good cables, computers and internet connection.

    Both of the scenario's I mentioned will cause your router to disconnect. You will not be able to access your router until it is reset, by either powering it down or using the reset button.

    My problem is you are not telling me if you have a telephone (non Voip) sharing the dsl line.

    If you do not then my suggestions are mute, and you possibly have a bad router. Did you try defaulting the router? Hold the reset button in for at least 30 seconds.

    Another cause I found is that the router's power supply starts to fail giving power intermittently.

    Not really.
    His problem is the router itself is failing completely to communicate with any computers connected to it (LAN). The DSL line has no impact on the routers LAN connection. Missing telephone line filters won't affect the router and interference from other wireless devices will only affect the access point, it won't affect the switched LAN.

    This particular Linksys router is a low end business class router which has built in functionality for VOIP...no Vonage modem would be necessary if one has VOIP.

    These routers are not built to last more than a half dozen years at best. The main cause of router failure is heat. Over time, soldered connections can crack and capacitors will go bad too. The next most common cause of failure is power surges, which will instantly (fry) or gradually (high heat instances) kill the router. Next is power supply going bad.

    Based on what Maroan has reported, the router has passed it's lifeline or the power supply is bad. Either case, I'd replace that model router with a better one, such as a dd-wrt Buffalo model.

    May be a bad piece ? Its more likely as I have low end equipment going on for 5 years or more.

    Much easier to change it than to troubleshoot it.

    How are you connected to your Linksys router ? Is it through cables or through wifi ? If its through wifi, its a good idea to change the channel & then see if this problem persists.

    I am connected through cables. I am still wondering why it kept disconnecting between itself and the computer... I had another Lynksys router that did the samme error, and it wasnt an old router either... there must be somewhere a bit of software that fails..
