Have the above device from the phone and the WLAN is very unstable.
At times, only very slow or no internet connection is possible with iPad, iPhone or laptop.
I'm now thinking about a replacement - maybe Fritzbox? They should run much more user-friendly and stable. Is that correct?
What I need:
at least 1 x LAN connection
at least 1 x DECT connection possibility
at least 2 x TAE connection for fax and analog telephone (yes, I need both).
Who can give me some tips?
A Fritzbox is certainly a good alternative
Maybe it helps to change the WLAN channel manually in the Speedport?
If you want 2 analog ports in the Fritzboxes, you only have the relatively expensive 90s models with S0 bus.
e.g. 7490, 7590 etc.
Almost everyone has DECT.
I would always buy a FritzBox with supervectoring, because then you will be able to switch to a faster DSL contract in the future (without having to buy new hardware). You'll get there faster than you think.
So I would buy a FritzBox 75xx with supervectoring.
