    Last night, I setup an old AirLink101 AR430W wireless router I have as a wireless access point. The router functioned fine as an access point except I noticed some strange ping behavior when connecting to the LAN through it from a desktop PC.

    When the PC was connected wirelessly through this access point, I could intermittently ping "www,yahoo.com". I would ping it once and get replies back. Then, I would ping it again and get a "host not found" kind of message. Then, I would ping it again and would get replies back.

    When the PC was connected hard wired through this access point (the AR430W has a 4-port Ethernet 10/100 switch), I would be able to ping Yahoo reliably and repeatedly. Once I switched back to the wireless connection, the pings were intermittent again.

    I did have the AR430W configured in "SuperG" wireless mode and the wireless adapter in the PC is a D-Link nano USB 'N' adapter (I forget the model). It was late so I didn't think to change the AR430W from "SuperG" mode to regular 802.11g mode.

    Any clues as why ping would work intermittently when connecting wirelessly and then work reliably when connecting hard wired through the same device, the AR430W?

    I'm just asking the question. The AR430W is no longer in service and I figure there's something wrong with the wireless part of the AR430W but I wanted to pose the question in the event there might be something else going on I wasn't aware of. :)

    Thanks!

    Peace...

    Only a guess, but I'd suspect the "SuperG" mode, as those turbo things are problematic when the AP and adapter are not a matching set.

    Thanks for the feedback. The other strange thing is when I connected to the access point using the PC with the N adapter, I experienced the problem. When I connected with a laptop with an integrated G adapter, I didn't have the problem.

    So, maybe the combination of "SuperG" mode on the router and using the N adapter caused a problem. I figured using "SuperG" mode would work with an N router, which supports up to 150 MBps speeds where I think "SuperG" maxes out at 108 MBps.

    In any event, thanks for the feedback. Your comment makes a lot of sense. :)

    Peace...
