Lately, my school network has had some issues. This extends across all wired networks. Network usability has decreased significantly, and loading pages for all users, from students to faculty to administration, has slowed to a crawl or even stopped. What I recently found out is that a wireless network was installed in a portion of the school, and serves about 12 or so computers, the most distant being about 75 feet away from the supposed access point (central to all the units) through two 6-inch walls.
I have two scenarios to explain the problem. First, we had problems last year during the winter months. We suspected that the cold weather, snow, and ice (this is a Chicago winter, mind you) had caused a problem with connectivity (this is still pre-wireless). While our provider couldn't give us a clear answer in this regard, it seemed to be a problem with their line somewhere. We still don't know if the weather could cause the problem, but it is a possibility.
The second and far more likely scenario is: the wireless network is causing a bandwidth issue. I suspect this is far more likely because we have periods of perfect working order on the wired network, and other periods of poor to no connection activity. This could directly relate to the status of the units that utilize the wireless network (whether they are on / connected or not).
The school runs on a T1 line and is known for having bandwidth issues when about ten computers run a speed-intensive download. Our bandwidth allotment per computer is not very high, but usually works well under normal operation.
My question is this: Can the connection of several wireless computers, even if Internet pages are not being actively accessed, impact a wired network that utilizes the same bandwidth elsewhere? I'm not sure what type of router or how many are being used for wireless connections; I only know that the connection is "b" or "g", units are set to acquire IP addresses automatically, WPA security is used, and the connection is achieved through the utilization of a USB adapter.
Also, if possible, I'd like to know what else could be impaction the bandwidth. Does an SSID broadcast consume bandwidth? Does the broadcast range have an impact as well? Is there another factor I may have missed?
Answers to any of these questions, and any suggestions that lead to resolving this issue are greatly appreciated. Thanks in advance for the help.
