Since doing this, the box, functioning without issue before, lockups up hard every one to four days now--and this is often reproducible when pushing a large amount of traffic through ral. I also see the following at various times in /var/log/messages and I do not believe they were there when I was running with wi--also, both cards are on irq 11.

It seems to be the sis that is the problem. Using ral with other ethernet cards doesn't cause the bug to show. There was a recent mail on the Soekris list from a linux user who noted that the sis still was alive but stops receiving. : When the card stops receiving it does still send data, I had a ping going from a wireless client, through ral0 to sis0, then to the remote machine.

Telcos have used a lot of wireless media - microwave links have been heavily used for long-distance networks long before the current low- cost equipment became available. Of course, they do the maths and know about leaving sufficient fade margins. Wire lines can also fail of course, but generally under different situations, so the two are often complementary. Much of the first spread-spectrum equipment to work in unlicensed spectrum came with the right connections to run E1/T1 over it. Dragging things back slightly more on-topic, wi(4) has proved very reliable; there has been some recent mention on soekris-tech (http://marc.theaimsgroup.com/?l=soekris-tech&m=114982978006733) about ral(4) stopping working after a while, though it's not yet clear whether it's related to soekris 48xx, or whether there's some interaction with sis(4), or whether it's something else.

The Surecom EP-9001-g has been good to me and I presume the other Surecom ralink-based cards (Surecom EP-9428-g and Surecom EP-9321-g) are good too. As a bonus I have never heard of Surecom fscking around with different chipsets in the same models. --- Lars Hansson

I'm determined to use an external antenna and already have > spotted useful devices, but not on the card side. 11g is supported by iwi, wpi, ral/ural drivers (no g for ath yet, also many ath vendors are now using newer chips not yet supported by the open-source driver). hostap is supported by by wi, ral/ural, rtw, ath. The intersection of the sets is ral/ural, if anyone's seen a cardbus ral with antenna sockets I'd be interested to know which one. (MiniPCI and PCI don't have much option but to use external antennas, of course, since they have to get the signal outside any RF shield/case). The newer radio cards most suitable for AP use are usually MiniPCI.

There are a limited number of PCMCIA/CardBus cards with external antennas (which you're likely to want for an AP), so you might be limited to B with the prism-based Senao/Engenius cards - wi(4) - they're reliable in hostap mode (as long as they are running supported firmware; see `man wi'). They seem to be quite widely available; Wim sells them, amongst others. If you want 11g hostap on OpenBSD, currently you need a Ralink device. Afaik if you want a decent antenna, this means PCI/MiniPCI (or possibly some of the USB devices). > It would be very nice if someone had a list of good current cards... Manufacturers change chipsets so often that maintaining this would be a major undertaking. If you want something that works you need to research, try cards, and when you find one that's good, buy any more you need before the manufacturer has chance to change design. Or buy from someone who already did this.
