Question about Linksys BEFSR41 Cable/DSL Router W/4 Port Switch, Retail Box (DSLSBEFSR41)
The router was working fine an all the sudden lost connection.Now we have to by pass the router to get on the internet what happened? I need the router working can you help me.
I have both, the Linksys's wireless-g router with speedboost and a linksysrouter 4 port router. At any given time either router can and does drop off. Continue with pasha19's actions, however I suggest before you start unplug the power to the routers. Using a pen press and hold the reset button at the rear of the routers for at least ten seconds. If using a DSL router do the same. Power all back up and continue with pasha19's instructions. Just doing the reset may give you back internet.

The following is not a solution but a set of steps to determine an issue. Wire the router back up -- connect a computer to it using a wire -- can it access the internet? If so the WAN side router config is fine. The issue appears to be a wireless issue. Did the wireless card lose the proper configuration settings to access the router? Did the wireless adapter disconnect and need to be reconnected?
If nothing above was an issue we need to do some other testing -- I do not believe this is likely in this scenario where things were working -- but as we have not yet found out a cause.
Turn all machines on before the test and do not turn off until after
On at least one wired computer that is working and one wireless computer attaching to the linksys router I want you to do the following
Click Start then All Programs then Accessories then Command Prompt
In the window that opens type
press enter then record all of the following for each adapter
you will either get 4 timeouts -- the connection fails or 4 messages with elapsed times generally measured in ms or milliseconds.
What you are looking for in the above
Good entries base
u should be unique for the linksys network
Wired IP address 192.168.1.u
SubNet Mask ?.?.?.? assuming 255.255.255.0
Default Gateway 192.168.1.1
DNS addresses ?.?.?.? not 0.0.0.0
where at least one is not zero.
Then wireless entries should be
Wired IP address 192.168.1.u should be 192.168.1.u
SubNet Mask same as wired
Default Gateway same as wired
DNS addresses same as wired
If these are wrong there is a configuration error either in the router or wireless adapters depending on how you want your network setup.
each connected adapter wired and each wireless should also
successfully ping the default gateway or router address
If the ipconfig is right and the wired config has successful pings, then every wireless adapter that fails has a wireless config issue.
If you are willing to work through this let me know and reply with information in a comment to this issue.
