I manage a student house with 10 bedrooms spread over 4 floors (basement, ground, 1, 2). There is a single ADSL line coming in to the basement.
Currently I have a modem/router (provided by BT, my ISP) in the basement, broadcasting wifi which the bedrooms in the basement and 1st floor can pick up. (4 people)
Wired from the back of this modem/router via cat5e cable is an access point on the 1st floor, broadcasting wifi which the bedrooms on floors 1 and 2 can connect to. (6 people).
The access point is set up correctly, I'm sure there is no configuration problems with the equipment, channels, etc. But the tenants complain of slow, intermittent internet access from time to time, probably peak hours. At no point does the wifi signal strength become weak, and at no point does the router in the basement indicate a problem with the connection to the ISP.
My question is, what is causing the slowdown? I cant see where there is a bottle neck in terms of the network and hardware. The only bottleneck that may exist could be a) the BT router being unable to handle traffic from the access point as well as the wireless clients when everyone connects at the same time? b) the ADSL connection being too slow to provide a service to 10 people?
Possible solutions are a 2nd ADSL line, or upgrade of routers. Which way would you go? The ADSL is approx 14Meg.
