#12428 closed defect (worksforme)

radio not transmitting? (wndr3700v2)

Reported by: anonymous Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: packages Version: Trunk
Keywords: wndr3700 Cc:


Version: r34064

Just upgraded one access point from r33288 to r34064 using luci and

Now it seems the 2.4ghz radio is working, but the 5ghz radio seems no longer transmitting (?).. at least I'm not seeing the network with my laptop, and also it doesn't show up with a scan from another WNDR3700v2 (older revision).
Scan does work on the r34064 though.

Could it be that it only receives and cannot transmit?

It's using channel 36, and I'm in Europe, so that can't be the issue AFAICT. It used channel 36 previously without any problems.

Let me know any commands you want me to run to debug it further.

# iw dev wlan1 info
Interface wlan1

wdev 0x10000002d

Just tried with r34093, same result.

Hmm. Just upgraded to r34122, which worked!
However, I did this on another AP instead of the one which had this issue, and I also used tftp instead of sysupgrade. I'll test the AP from the bug report later with this new release, first with sysupgrade, and if that failed with tftp, to nail down where the actual problem was.

Upgraded the router with this radio problem to r34122, still same problem.
Then I upgraded it again but unchecked the 'keep settings'. Now it works.

I've no idea what the problem is/was, but at least now I can test if #11894 is fixed with this new firmware.

As far as I'm concerned, this bug report can be closed, even though it isn't technically resolved...
