Switching on TV hangs up the router

Postby aterentiev » Thu Apr 12, 2018 1:05 pm

I couldn't beleive, but my smart-tv, which is connected to the router wirelessly, hangs up the router immediately after being switched on, almost every time. This is a LG TV, in the list of web usages I can see some sites visited by the device, but nothing else.

It happens not every time, but very very often. I switch on the TV, all WiFi devices lose the connection, only a power cycle of the router can bring the device back into life.

What could it be? I had the same issue with the release version 1.10 as well with the gargoyle-ispy 20180221-1931 the ispy version is a little bit more stable. The hardware is TP-Link TL-WR1043ND V1.

Any ideas?

There are many things it could be.

We know the firmware is stable

Try a fixed cable for an experiment

Try change wifi channel

Upgrade TV Firmware

I've been witnessing some similar weird behavior on my 1043nd V1 - see my thread about 'Faster wifi' with this router. I'm finding actual Gargoyle firmware quite stable (using officital 1.10 release as beta firmware seemed to slow-down massively after heavy benchmarking so I just guess it leaks memory somewhere...) - but for WiFi you can try to deploy these 2 tricks:

Update your /etc/config/wireless with these settings
(note especially txantenna,rxantenna,htmode)

Code: Select all

config wifi-device 'radio0'
   option type 'mac80211'
   option path 'platform/ath9k'
   option country 'US'
   option hwmode '11g'
   option channel '3'
   option txantenna '5'
   option rxantenna '7'
   option htmode 'HT20'
   option txpower '23'

Put your corner antennas into this position:


And for middle one keep whatever position give you 'faster' network.

Always useful to read links like: https://www.alltechbuzz.net/boost-wifi-signal-strength-at-home-2016

And if you are into hardware - you can just validate if some capacitors on this rather old hardware isn't malfunctioning as I'd to replace one myself as well - see how to recognize dying one:
