Hi All,

In one of the place that I'm managing (server is using Windows SBS 2011, clients are using Windows 7), they have multiple wireless AP.

These wireless have different channels but same SSID; which means users can move around without being disconnected.

Question:
- Is there GPO policy to detect wireless strength (in dBM); and if it's lower than certain level, reconnect to different channel; if not just stay connected to it

Thanks all

User login process takes an ages using wireless

As the location of APs are quite close each other, I noticed there is time Windows connected to the furthest AP, in which has slower transfer rate.

Furthermore, someone mentioned to change 'roaming aggressiveness' setting. Currently set at medium, I'm changing it to low now and would monitor whether this make it better.

It would be nice if Windows can monitor which channel it connects to (instead of using third-party such as insidder)

are many people attempting to use the wireless at the same time? if so the connection will be greatly slower for every extra device as wireless acts as a bus system.

what sort of wireless access points are you using? if you have many users replacing them with Mimo access points (ones with multiple antennae) can help congestion greatly.

In total there are 15 machines using wireless.

The AP model is Cisco E-2000 (http://m.cnet.com/reviews/linksys-e2000-advanced-wireless-n-router/34103434)

Can I use GPO slow network detection to trigger wireless reconnection? And hoping it reconnects to the faster/closer/better dBM?

after having a look, you may want to increase the roaming aggressiveness of a machine and see if it helps.

also check what channels are being used by your neighbours and see if there is congestion on the channel which can also decrease your performance, with 15 clients the wireless is not going to be greatly fast overall.

try inSSIDer on one of your machines and walk around and checkout what the local congestion is like, it could even be that your neighbours are all on a channel close to yours.

If I increase roaming aggressiveness, would that mean the machine keeps looking for fastest AP and connects to it straight away? I'm afraid if I increase it too high, it might gives too much reconnection process during boot/login process

What do you think?
