I am experiencing problems with my SA520W.
The SA is connected to a motorola broadband cable-modem. WAN connection is fine with good response times.
If clients are connected via cable to the SA, the overall performance is very good.
If clients (3 Windows 7 PCs with N-standard) are connected to the SA via WLAN, I am expeiencing an unpredictable behaviour in connectivity and ping response times from the SA.
WLAN connectivity itself is good (approx 15 meters from the SA).
Sometimes clients can connect without problems, sometimes not.... (need 2 or 3 manual reconnects).
If a ping -t is initiated from the client to the SA, it is normally below 2ms.
If a browser is started (eg. Explorer8 or Mozilla) connectivity is good for a short time. After a while, ping degrades to eg. 400ms and gets worse after a minute to over 3000ms.
I have no idea, what could cause this behaviour, since a wireless connection doesnt show this effect.
Same effect with mixed radios/standards (N/G)....
Firmware is the newest.
If someone has a good idea, please give me a hint.
If more informations are required, tell me what you need.
Thanks for any help!
