Re: Broadcom wireless driver detects other routers except mi


[re: mrdigital03] [link to this post]
 
Surely this is more to do with on the driver side rather than router side
So does it work on Channel 11 or lower ?

If the driver has a binary blob that doesn't extend beyond channel 11 it will indeed be the fault of the driver, but it's in your hands to change the channel on the router.

I dont have admin access to the router settings. So would not be able to try that out frown

Don't have router admin access to test this theory.

Just one more thing - in the OP you mention two different drivers, have you tried both after changing the regulatory domain to GB (with "iw reg set GB") ?
Just in case one can do it and the other cannot.

Aha. I got confused by "Also if the channel is reduced to a lower level, it results in wireless drop out issues on the other devices.".

Can you check the output of the "dmesg" command again (or post it) to see if the regulatory domain has changed correctly? You should see something like:
cfg80211: Regulatory domain changed to country: GB

If not, it's back to try to think why it isn't set correctly...

Sorry about that, I should have explained; Basically a few months ago the admin had changed the channel to one of the lower ones and there were drop out issues (maybe due to the fact of similar freq.shared by other neighboring routers) So they don't want to change the channels again.

Re: Broadcom wireless driver detects other routers except mi


[re: mrdigital03] [link to this post]
 
Hmmm, that looks all correct.
Which leaves the drivers, both of them, not being able to use channel 13.
Or else something none of us has thought of yet.

edit - this seems to confirm that both drivers aren't able to see channels 12 and 13: http://ubuntuforums.org/archive/index.php/t-2087718....
