Strange problem

for some strange reason every so often (say once every half hour) a strange thing happens - its almost as i broadband disconnects - i get 0 bandwidth and cannot load webpages etc - after a while my bandwidth comes back up - but this problem means i cannot download large files or play online games. i dont think its a problem with plusnet as nobody else has reported it - im using a netgear dm602 broadband modem with the latest firmware, and a linksys broadband-b wireless router - although the computer i mainly use is conected to it via cat5 cable rather than wirelessly - the operating system i use is debian linux and i havent tested this with windows - does anybody know of a way for me to narrow down the options (ie to be sure its my computers fualt)?

Strange problem

nothing seems to be apearing in my logs - im guessing because i dont use the router as a dhcp server - my network uses static IPs, with the gateway IP configured as the modem, also my modem is pluged in to the socket specified on the router for the internet as i couldnt seem to access it that way

Well, as you have not given any info on the router you have (make/model etc) it will be difficult to advise what you need to do.

It also depends on the equipment as to what the logs actually record, however not running DHCP and using static IPs will have nothing to do with you not seeing any log events. I suggest you read your manual which should explian what to do.

Also it is actually the ADSL side or the router that is important for your problem - i.e to determin if your connection is dropping out, although as you have a separate ADSL modem the router logs may npt actually record anything related to that. Does the ADSL modem have any logging capabilities as that is where your problem may be recorded.

Strange problem

the linksys router is a befw11s4 broadband-b wireless router. very strange - whilst trying to access the modem to check its logs, i typed in its address on the network into my browser, the password prompt came up as usual - i typed in the password - but then the modems configuration pages didnt load at all (i waited a few minutes) - at this point i could ping the modem fine and get on the net fine, and it wasnt the routers fault as i was directly conected to the modem, having detached the router from the network temporarily.

having turned my router off and back on again i can now get into the configuration pages. it has an alarm logs section and the log looks like this:

connected directly to the net without the router i still get the original problem, so presumably it isnt the router thats at fault

Strange problem

a customer of mine is getting the same problem and has for a few weeks, so I swopped out his dlink504 for a netgear router and the same problem persists with both devices, just random drop outs.

wonder if its a bt problem?
