Guten Tag,

****************************Original text below****************************

Sorry for writing in English, but unfortunately, my Deutsch isn't very good yet.

I have a  Speedport Smart that I use as a router and DSL Modem at home.

I have noticed that when I connect to the Speedport WIFi, I experience unstable internet coonection, i.e., when I use the browser (Firefox or Chrome) on my tablet or smartphone, I will often get pages that suddenly stop loading or the timed out error page.

This does not happen when I am on my computer  that is connected to the Speedport via cable on the LAN.

As a test, I connected a second router (TP-Link) to the Speedport LAN via cable. I then connected my devices to the TP-Link router via WiFi and found that I could connect to the internet without any instability. I repeated this many times over several weeks and the results have been the same.

Can anyone suggest why I am having such difficulty with the Speedport?

with thanks,

Al.
