[Solved] Wireless problem

Postby toothandnail » 04 Aug 2013 01:42

I've got two different MiFi devices. Both are Huawei - one is a Huawei E582, the other and E586. The 586 is the newer and is a bit faster, as well as having better battery life than the 582. However, I have a bit of a problem with it.

When I first fired it up, I found that I could not connect to if from Arch (which is the distro I tend to use most on my laptop). Initially I thought it was a problem with the device itself, but I then found that I could connect to it from SolydX or Salix (both of which I also have on the laptop).

I got a second SIM with a limited amount of data so I could try and isolate the problem and get it to connect from any Linux distribution. Unfortunately, the alternate SIM is on a network that doesn't have very good 3G coverage in most of the areas I work in, so I'd been putting off investigating until I could get a better connection. Apart from which I've been pretty busy and haven't found the time to get back to it.

A few hours ago, it got to the top of my to-do-list. So I fired up SolydX to have a look at what the thing was doing. Only to find that, since the last UP, I can no longer connect to it from SolydX either. So something in the last UP has caused the same problem I've been having with Arch.

The problem appears to be a failure to authenticate against the WPA2 in the E586. Thinking it might be wpa_supplicant, I used the Arch Rollback Machine to revert to an earlier version of wpa_supplicant, but found that didn't help. So I'm still stuck.

I've looked through /var/log/apt/history.log but find it very difficult to work my way through. So I'm wondering if there is a list of all the packages that were updated in the last UP - maybe I can narrow the search a bit, since I know it was working before the UP went in, and isn't now. I still think it is failing during authentication, but I'd really like to see if there is some other package (a library maybe) which is influencing the authentication failure.

Any other suggestions for sorting this one out would be gratefully accepted.....

Paul.

according to https://bbs.archlinux.org/viewtopic.php?pid=1301702 that points to the bug report here >> https://bugzilla.kernel.org/show_bug.cgi?id=58881 it's a regression on the 3.9 series
the fix commit was issued on the beginning of june
with the due delay we should expect that kernel 3.10 has this fixed
bliss of ignorance

Well spotted. I did some searching but didn't find anything. That is is exactly. I'm running kernel 3.10.3 in Arch, and hadn't tried the newer Huawei in Arch for a while. Using it now - connected without problems!

:) Now all I need is a 3.10.x kernel for Solydx as well....
