Huawei P8 lite Wlan slow?

I have the Huawei P8 lite for 2 years and so far, the Wi-Fi has worked properly.

Unfortunately, but I have a couple of days Wi-Fi problems, I've already tried everything, reset to factory settings, etc. It brings nothing.

I have, according to the router interface, a speed of 100 Mbit / s and a really good signal strength komman but on my phone only 1 Mbit / s.

Quite possible.
Funk is just unstable.

That a software reset is done nothing is not surprising. What should this also change the situation of the radio waves in your WLAN? Nothing.

Possibilities:

You have had a new source of interference in your area for a few days
If other devices are working normally, the Huawei's Wi-Fi feature could also get out of hand. (Defect, wear, …)
If all devices were slower synonymous your wireless router could have a head away. (Defect, wear, …)

Yes, the wireless feature of the phone is broken, you can do something there. Unfortunately, the warranty has expired. Can you fix that at all?

Phew. Guess as you can exchange little except the motherboard of the phone. With such handy devices, there are no plug-in boards that you could easily replace as with the PC.

But: Whether the exchange of the board is profitable I can't judge.
