I'm having several issues with the USR 5461:
1) Wireless network drops after 1-3 days without warning
2) syslog configuration does not work
3) built-in logging is more or less useless
Wired connections are stable, so is the Internet connection. For 1) using the reboot function in the Web admin interface of the router using a wired laptop resolves the issue.
I'm using WEP, no MAC filter and the clients is a combination of Windows XP laptops (with and without VPN), two Apple PowerBooks with Mac OS/X 10.4+ and a Terratec Noxon Audio Internet Radio appliance.
I am in contact with USR support and I will send them the router for a replacement. They say that they are not aware of any issues. In any case, they will replace the router. I will add my experiences with the replacement item here, later.
Anybody else out there having wireless network stability issues with the USR 5461?
