Edit: NM, wrong thread 
2.9.25 should be out this week (today or tomorrow hopefully)
I can confirm that 2.9.25 fixes the problem with the Intel 3945abg and the Atheros AR5213 chipset. All is well again. Thanks Mikrotik.
doesn’t work for me with Intel 3945abg and Atheros AR5213.
The testing laptop is a HP nx9420 with the Intel 3945abg card builtin.
The MT is in ap-bridge mode.
Do I need to do something special with the config or something ?
I was set to 2.4Ghz-B/G, no Nstreme, no compression, preamble both, no wds, ap-bridge mode, no encryption.
Finally got it working!
I got it working after setting the new setting
“Proprietary Extenstions” to “Post-2.9.25” insted of the default “Pre-2.9.25”.
From where the setting is in the GUI I can’t understand why this makes any difference at all, but it does!
I got three different AP(two VirtualAPs) and I tried having them in different settings and always when I switched from pre-2.9.25 to post- it shows up in my intel card and after switching from post to pre it dissapears!
Well.. anyhow.. it works now and that is all good!
Thanks MikroTik!
Well, this is encouraging. Will deploy tonight. Thanks.
I can confirm that it works with 2.9.25 with the post-2.9.25 setting.. Compaq hp8440 with intel 3945abg.
It was funny fighting all day with this issue on a holiday, next to the hotspot antenna and not able to connect. :roll:
