I live in 15 story student accommodation building that only provides wireless internet. My laptop has a built in "Intel(R) WiFi Link 5100 AGN" wireless adapter. I've been observing the following pattern when connecting to the college wireless network:
- Connect successfully, the network icon in the system tray shows like 2/5 bars for the signal strength. All is working well, speed is like ~2MB/s, skype video calls work flawlessly.
- About 10 minutes pass and the signal strength seems to get better, eventually it reaches 5/5 bars in the system tray. However the connection speed starts dropping exponentially to like ~200 kB/s or less, it becomes very unstable, skype video is virtually not working and keeps disconnecting every few minutes.
- I reconnect to the network manually, everything works very well again, strength 2/5, the pattern repeats itself.
My guess is that my network card decides to switch access points after sometime, since it discovers a better signal, but that signal turns out to be worse for some reason. I verified this in part by changing my wifi adapter setting of "roaming aggressiveness" to the weakest. Now the signal stays at 2/5 for a half an hour or more, but eventually it still reaches 5/5 and I have to reset the connection manually. I also noticed that my android phone does not seem to have this problem, it connects to a weak signal, stays with it and works very nice.
So my question is: is it possible to somehow observe the access point migration, i.e. confirm my suspicion and if this is indeed the case, is it possible to force my adapter to work with a specific access point ?
