Router is TP-Link TL-WR842N/ND v2 on openwrt 14.07
Everything worked like a charm but recently started to happen strange things.
Sitting at the tablet as he suddenly disconnects from wifi and cannot connect to the router. Says no Internet or something that can not obtain ip by dhcp.
The laptop is on Ubuntu connects fine to wifi, but the Internet is slow.
And as I noticed, it stops only on wifi. PC connected via lan wire is working as usual, speed takayazhe (measured speedtest).
In the log of the openwrt kernel no errors. In system log also no errors. Load 0.01 0.03 0.05 on average. The active compounds
195 / 16384 (1%)
All this continues until a reboot of the router. After the tablet reconnected and Internet on wifi again, fast. And how to explain it.
Again the router is the minimum load/not filled nearly RAM/no errors in the kernel log and system log. But the Internet connection to become slow and not stable. All this continues until a reboot of the router.
