Ubuntu 8.10 + Ubiquiti SRC 300mW PCMCIA?

[pento]

Hello, everybody!

There is Lenovo T61 with internal wireless Intel 4965AGN. OS: Ubuntu 8.10
+ Ubiquiti SRC 300mW PCMCIA with standart antenna (ath5k driver)

It's strange but internal card looks more powerful: signal much better.

What is the best configuration (drivers) for this card (Ubiquiti SRC 300mW) to work in Ubuntu 8.10?

I can only confirm you the same.

With my HP nw8440 under Ubuntu my internal Intel Pro/Wireless 3945 is much more sensitive than the Ubiquiti SRC connected to a 9 dbi antenna.
I'm using the ath5k driver but it was the same with the older madwifi driver.

Of course under Windows the SRC is much better.

I wonder whether this is Linux driver problem.

Any suggestion is welcome.

Have you guys tried the Windows driver?

As already written, the SRC under Windows with native Ubiquiti driver or Commview driver provides excellent performances.
The problem is under Linux/Ubuntu-

Hi!

With Ubiquiti SRC 300mW PCMCIA with standart antenna + yagi antenna 15 dbi , so diversity mode with ath5k driver (kubuntu 9.0.4)

I have same performance under kubuntu 9.0.4 and windows xp pro... maybe more sensitive under linux.

I changed the Kernel in Ubuntu 9.04 and signals are fine now altough I still notice better performaces under Windows XP.

Hi!

Try to install last build of ath5k :
http://wireless.kernel.org/download/compat-wireless-2.6/

For me, Windows driver is clamped (cause regulatory domain is in action with 20 dBm by default), if I compare informations between window and linux driver:
- 200mW, 24dBm for window
- 501mW, 27dBm for linux

But what is a real wireless test ?
- what is your AP, your card revision and chipset, antenna
- what is the encryption : open, wep wpa, wpa2
- what is climatic conditions: rain, sun, wide, humidity...
- what is environment: garden, wall, iron structure
- what is donwload result, upload result

Too much parameters for really compare your SRC with mine...

hi,

well compat-wireless is a good thing, but in my case didn't work as well - even
with latest one.

Also keep in mind, in case of backtrack 4, you are also unloading madwifi-ng
drivers and therefore having issues with other cards with injection, monitor mode etc.
