Slow WiFi

[adm1neca]

Hello all,

For some time now (several weeks at least) i have issues with the WiFi... It is terribly slow at times.

 Just now, performed the speedtest on the ziggo website and got c. 20mb download and c. 10mb upload... Far below the promised 250-300mb download speed (I know it is 250mb for cable, but still - WiFi should not be that slow). Router is Technicolor TC7210 and have it for quite some time now.

Possible solution: Give 2.4 and 5 GHz a different Wi-Fi name and connect to 1 of the 2. Also check with Wifi Analyzer, download from the app stores, whether the neighbors are not on the same channel, otherwise set your own WiFi to a different channel and fix it.
