Wireless LAN problem

    I have a Buffalo 802.11b wireless router, have had it for a long time but only started using it now. I've noticed that when pinging wireless clients that there is occasionally a packet which takes a lot longer to get there, and very rarely it is lost altogether. Here's a ping I performed from my PC (wired) to my sister's (wireless):

    The access point is 802.11b as I mentioned above, but the cards I'm using are D-Link DWL-G520+ 802.11g (54Mb/s) cards. I also have a DWL-G650 Cardbus card in a laptop, same problem. If I ping the access point from a wireless PC I also have this problem, but if I do it from a wired PC then it works away fine.

    Is this a compatibility issue or a fault with the access point? Or is there any other advice you could give me?

    Do you notice degraded performance when using the network?

    I'm not 100% sure at the moment, its only been online for a few hours. So far its just been used for the internet so its hard to tell.

    Signal strength seems fine by the way.

    I think I've answered my own question. I found an 802.11b PCMCIA card lying around so I put it in a 486 laptop (lol, yes it actually can take it!). The card doesn't have any brand name, seems to be one of those cheap unbranded jobs.
    If I use the laptop to ping a PC with one of the D-Link cards I'll get the delayed or dropped packets. But if I ping my PC (which is on the wired LAN) I don't lose anything, I sent 213 packets and got a maximum of a 5ms ping.

    So it looks to me like the D-Link cards don't "like" my access point, maybe because they're 802.11g rather than 802.11b. But I'd assume they'd be backwards compatible?? :confused:
