Vigor2860 Firmware v2860_3744.zip was created by chocksaway
I have a Vigor2860Vn+

I have just upgraded the firmware to v2860_3744.zip (Firmware 3.7.4.4 - http://www.draytek.co.uk/download/support/v2860_3744.zip).

I installed this, and everything attached to my wireless LAN "lost the wireless network".

The root cause is the strength of the 2.4 ghz network went from strong, to nothing. I moved to channel 6 (from 11), but there was no difference.

I rolled back to 3.7.4.2, everything is now back to normal.

I would strongly recommend that you are cautious with this upgrade, if you have a Vigor2860Vn+ box.

Thanks

Miles.

I note that DFS support has been added in 3.7.4.4 so when changing 5 GHz it'll stop broadcasting for 60s, but that doesn't explain why 2.4 would not be broadcasting...

HI

Same issue here, I have a 2860n-plus

As soon I upgraded to 3.7.4.4 the 2.4GHZ network disappeared.
I can scan network but all the devices cannot see the 2.4GHz network.
The 5ghz is fine.
It looks like is a FW issue

Furthermore... the draytek tech support have no idea of the problem.
They keep saying there are no known issues with firmware 3.7.4.4

Weird one. An idea - try taking a backup of the cfg and then .rst flash with 3.7.4.4 (which will factory reset as well) and afterwards reload the cfg.
