In HOSTAP mode, you can have one roaming STA, or you can have several STAs if they stay in almost same TX/RX condition. This limitation is primarily due to ural (same applies to rum) hardware does not have per-packet (or at least per-peer) TX try/fail counters. This can't be fixd by driver.

Re: USB wireless AP?
I've found a perfect match for my needs: D-Link DWL-G122, with the rum driver. Not a single problem so far, everything works as documented. Truly a plug and play experience. I'm just curious about one more thing: I wish to set up a b/g network, so both b and g devices can connect. Apparently this is set up via the mode argument to ifconfig, which accepts 11g and 11b but not the obvious 11bg. Any pointers on this? signature.asc Description: OpenPGP digital signature

You can either omit the mode argument altogether and get both supported by default, or just specify 11g, which will also support both. I typically omit the mode unless I want to limit things to only 11b.

Do you know about http://ralink.rapla.net/? The RT2500-based cards listed there are supported by the ural(4) driver.

Can anyone recommend such USB wireless hardware, preferably in terms of product names instead of chip names? I see the following cards in a local store: BANDRIDGE CWN4002G, CANYON WF-518D, CANYON WF-518, LINKSYS WUSB54GC. - Are there any tips tricks additional to the instructions on http://www.freebsd.org/doc/en/books/handbook/network-wireless.html ? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Are there any practical differences between HOSTAP and IBSS when used by a very small number of users? I've never used IBSS, but I have enough spare 802.11 hardware to try it out.

Re: USB wireless AP?
I would reference the link that I am about to list. I would also reference googling the topic, since there are quite a few USB wifi adapters that work, however, it seems a bit more difficult to find people who are using them as AP media. The atheros reference pdfs reference a different chipset than what we usually deal with on BSD ath driver. (5512, or some such.) I forgot about the prism based cards, which the following link is in references. http://osdir.com/ml/os.freebsd.devel.hardware/2006-06/msg00034.html The SWEEX model LW053 is also compatible, however, it uses the rawlink RT2500USB chipset, so I am not sure how the access point functionality will work, since it may be suceptible to the previously referenced warnings within the driver manpage. Is there a particular reason that the USB adapter concept is needed for your application?
