Default Re: Very Basic Router Question


Thanks for the help!!

When I lost my internet connection, I quickly eliminated the router
and connected the PC directly to the cable modem.

Internet connection remained unavailable for 2 minutes, when it came
back without my doing anything.

I then put the router back in the loop and connection remained stable
as it still remains, 3 hours later.

I have an old Motorola SB4200 Surfboard modem and don't seem to be
able to find anything about how to check signal strength or
diagnostics, at least on their website!!??

You said:

>You can can get signal level statistics from your modem status page.


Not sure about that at all......

My setup has been rock-stable for years......both TV and internet, but
has had these intermittent problems for the last month or so. No
splitters or amplifiers.

I don't think it's on my end, but that's hard to prove.

(The last problem I had was intermittent log-in timeouts with my email
accounts. RoadRunner suggested that I do everything under the sun,
include reformatting my HD and calling in experts. Long story short,
our town had a power failure, once it was restored, I had even more
email problems that night, but the next day it was back to perfect.
NOTHING at all was changed on my end and somehow it was fixed!!!)

thnx
