Hi there,

Im currently stationed in Japan, I live out in town with 4 other guys and were running a WLAN in our house. We have a DSL connection.

Now here is our problem:

We have about 5 computeres connected all on a wireless connection to a router
(US robotics wirelsss turbo access point and router)

Now our wirelss keeps dropping the internet, sometimes it will work all night, sometimes only 5 minutes sometimes an hour, then it will drop for maybe...1-5 minutes and pop right back up.

It seems at night starting around 11 it wont drop any of us until the morning. Also a few of the guys play internet games and it seems to drop more often when they play them. But sometimes it just drops. we are all on labtops.

Now I think its a bandwidth problem as we have problems talking with the internet company because well they speak japanesse and us english but im not 100% sure.

is it that we just have too many computer useing too much?
I have also read it might have something to do with signal strength?

any ideas would be greatly appreciated.

Thanks!

p/s sorry im not the most computer literate person and know very little about LANS so if I left out some important information please tell me =)

Well I ain't the best guy to answer your questions but it does seem a straight forward example of "low bandwidth" sharing.

You have to remember also that there can be 25-50 other people in your street/area on the same line ... that is a simplified way to put it. And as they go to bed at 11, you then get better access.

I would be searching for a "friend" who speaks Japanese to help with the ISP side.

Nick, it might be worth finding out what capacity the circuit has, ie. Is it 1MB downstream / 256K upstream, and also what the "contention ratio" is.

In simple terms:
Downstream = The line capacity for downloading data to your PC
Upstream = The line capacity for uplodaing data to the web
Contention Ratio = The maximum number of connections which share the circuit at the exchange (This is not the number of people sharing the terminal connection from your router).

It is possible that there is a really low capacity with a high contention ratio, which simple means it wasn't designed to have too many machines hanging off the end of the router.

See what you can find out and come back to us.

Good luck, CI
