Hi,

The compagny Comminter ( http://www.societe.com/societe/communication-interactive-441996279.html ) would like to offer 250 euros (via paypal) for anyone who succeeds in solving issues related to the mt7603 driver on wg3526.

Namely,

We can also offer free wg3526 hardware, if needed.

Regards.
Pierre.

I think I'm having the same issue, or related.

Using LEDE Reboot 17.01.0-rc2 r3131-42f3c1f / LuCI lede-17.01 branch (git-17.032.85243-5f80115).

Almost every day I get this:

@pparent76 i doubt that 250 euro will change anything. According to @corny (who has the info from the driver developer) the current driver is just an early prototype.

from mt76.

Please try the latest version

from mt76.

Duplicate of #32

from mt76.

I'm using 17.01.0 since several weeks ago, and still having the same issue.

Or do you mean snapshot build Wed Mar 15 04:46:10 2017 ?If you mean something else, please provide the link so I can try it.

from mt76.

I just pushed the fixes, a snapshot hasn't been built yet. You need to test the master branch r3749-64170ab925 or newer

from mt76.

pls can someone update me, when a new trunk version was built with new fixes so, that i can test ?
in newer lede built also included ?

from mt76.

The fix is only included in LEDE, not in OpenWrt. A new snapshot build is available, so you can test now.

from mt76.

I've tried it with the latest trunk from today, and in just a couple of hours, I already got the same problem. I will try anyway, during all the weekend.

I'm happy to test anything you need.

i guess it is a different bug ...
better would be to open a new ticket for it ....
