    Router stops responding with red alert light turned on problem

  • fiona_ru Nov 25, 2007

    Router stops responding, red led "alert" is on.

    No connection with router on http.

    Restarting the router is by disconnecting from power and after router reboot solves the problem

    Just disable SPI, Hacker Pattern and Anti-Dos Firewall and everything works fine!

    Hi i have a problem with my wireless router

    wireless router 3com 3crwdr200a-75 stops from entering to the net. I power it off and switch it on and it will work normally. But that happens more than 5 times a day, and each time i have to switch off and power it on !!



    any solution ??

  • Tony_lunna Mar 01, 2008

    I had a similar problem - alert light on and modem locked up, no wireless or lan access. I have updated to the latest 3com firmware 3.0.1 But, beware : after the upgrade, it is necessary to do a hard reset as follows: power off, press and hold in the reset button on the back panel, power up but keep the reset button held in for 30 secs, release the reset button and allow the modem to complete its boot up. Once this has completed, power cycle again without pressing the reset button. This is the advice I was given from 3Com. The soft reset from the menu should not be used. All settings will be back to defaults, including the lan ip address (192.168.1.1). Tony.

SOURCE: Router stops responding with red alert light turned on

Is the actual router not responding or the internet?

(IE - can you still log into the router but the internet won't work, or will it not even connect to the router)

I bought a 3com 3crwe554g72 and when it connect with my ADSL modem the speed will become very slow (-50%). I update to the lastest firmware but no help


3com used to be good things back in the old days. But this hardware is probably self destructing in some way (the problem is widespread, the manufacturer claims it is an old product and gives no solution). Do NOT buy network products from 3com (HP today). Correct me if I am wrong..

Ugrade 3com router 3CRWDR200A-75


The first thing I would check would be in the configuration (point your web browser to 192.168.1.1 when you have a wired connection) panel, under:
Wireless settings > configuration

If the 'Wireless mode' is set to 'SuperG', this may be your problem. The SuperG setting will only work with SuperG enabled wireless adapters. First change this setting to 'Mixed 11b/11g'; if it still doesn't work switch down to '11g' then to '11b'.

Do all your wireless testing with a laptop or PC as close to the router as possible - same room at the very least.

If all other settings are correct (double check them), this is the only thing I can think of that can instantly make a difference.

If you feel the firmware may be faiilty, note that although 3.0.1 is the 'newest' on the 3com website, even in their own knowledge base they refer to newer versions. These newer versions are available at:
http://3crwdr.googlepages.com/

You could try using one of these (at your own risk), if you feel it is the firmware itself that is causing the fault.
