it works perfect with WEP when I use it as Access Point. No longer another AP available to do other tests. I did not test it as a router as I use it downstairs for my laptop, but the other ports are used for local pc's downstairs. If I'm not at home and the wl500g may give a problem, at least 1 pc can work with the UTP that takes care of the signal from the main router, simply by moving the UTP connctor from the router to that pc . All pc's have fixed IP (for ftp et al) and if I would put the wl500g as a 2nd router the easy switching would not be possible anymore (2nd gateway) without chang in the pc-settings. I prefer to avoid that for my home users.
With my laptop I can have UTP and air connection (of course of different ip nrs... ). The moment I active WPA-PSK by confirmation in the Asus WLAN tool... all traffic stops, while the HF is r3ceived (signal indicator). When I turn of the wireless card I get back my LAN-UTP connection and after applying WEP both stay connected ("LAN-UTP" and "WLAN-air").
edit: since this morning I loose also connection with WEP ..... Restarting notebook and WL500g and reconfiguring do not help. When I shut down my WLAN connnection I get back my LAN...
Same problem when I go back to the latest .50 firware from Asus. Strange problem...
XP firewall is off and I checked also with Zonealarm off, no difference. I will try a complete re-install of the wireless on the notebook. I prefer not to reinstall my complete notebook...
