Ok, so here is a weird one. I used to have a netgear modem, worked great for years. A month ago, the connection starts dropping on all devices (i have one wired desktop, and multiple wireless such as blue rays and ipads etc). My high speed cable company determines its the router. I do too, when the desktop is only plugged into the modem things work fine. After multiple reviews, I purchase the E1550. It works fine... for a month...
Now I am having the same problem. I went as far as exchaning my E1550 for a new one from Best Buy, but same problem. The connection will drop on all lines, hard desktop and wireless devices. Sometimes it happens once every hour, sometimes every 10 secs. I have changed settings on my router until I am blue int he face. Id ropped the channel width to 20mhz and tried multiple channelts. I lowered the beacon intervel and fragment threshold RTS etc.
Also, as a side note, my hardwire desktop will not connect to the router through the cisco connect icon, even when internet is working. It says 'cannot access router' even when i have connection. I am making all changes through the browser typing in the ip in the address bar. Any other ideas?

If you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the user name field blank. This will take you to the router's web interface.
Then under the Basic Setup page in the Router management page lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less. Here is the link for determining and setting up the correct MTU size: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=

You should either try to upgrade the firmware, or if you have the latest one, try to reflash it (upload the same firmware as you have now) since it's one of the workarounds to clear buggy performance of the router.

Thanks for the advice guys. I have the latest firmware and I tried lowering the MTU prior. It seems like some kind of IP or IP refresh conflict. Its almost like the modem doesn't communicate with it properly.

You can try the following settings as well:
A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
1] Open the software and go to the option which says "Router Settings"
2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
3] Then click on Security tab disable SPI Firewall Protection, uncheck Filter Anonymous Internet Requests...
B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the user name field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.

Hi there. Is your device still working for internet connection? How did you connect to that address? Try opening up the command prompt first (start>run>type in cmd for XP/ start>search>cmd (Vista&W7). Once you have the command prompt open, type in ping 192.168.1.1 and press enter. If you are getting 4 lines of Reply from, then that means the router is responding. Open your internet browser and type on the address bar: http://192.168.1.1.

Hi, I tried pinging and got the four lines showing a succesful connection. However, I still get "Firefox can't establish a connection to the server at 192.168.1.1." message.
Suggestions?

Hi. Try a different browser then like IE or Chrome. Are you on XP, Vista or Windows 7? You can try to check for proxy settings on your browser and disable it. Or try this: open command prompt and type: start http://192.168.1.1. Your browser should come up and I hope you get the prompt to log-in to your router. If that still does not work, try another computer and do the same steps. If that would fail still, reset your router for 30 seconds and unplug it for 30 seconds.
