Wifi scan via luci do not work in BB rc3 on TP-Link WDR4900 v1.

dmesg says "luci[2857]: unhandled signal 11 at 816be0a8 nip 480dc9e8 lr 4801ecc4 code 30001"

"iw dev wlan1 scan" do work so it seems to be a luci related problem.

Anyone else who has notices the same?

Post the output of "opkg list_installed | grep iwinfo" please.

iwinfo - 50
libiwinfo - 50
libiwinfo-lua - 50

same here on WR941ND.
However, if I disable the existing wifi (hotspot one), then the scan will success.

libiwinfo - 50
libiwinfo-lua - 50

I havent installed iwinfo

I have similiar problem with TP-Link TL-WR842N/ND v2 and OpenWrt Barrier Breaker 14.07-rc3 / LuCI Trunk (svn-r10467)

Command line scan works but luci hangs on scan request.

I'm almost facing the same issue.
To be more specific, luci shows nothing...

I also noticed there is an open ticket:

Has this been fixed?

Same with two 741s  Barrier Breaker rc3: Wifi scan crashes via LuCi

Yes the problem has already been fixed and should appear in the next binary builds. You can also try to update just libwinfo from the snapshot repo, e.g. https://downloads.openwrt.org/snapshots … ar71xx.ipk for ar71xx, that should solve it already.

Installing this package on BB RC3 fixed the issue for me. Thanks.
