Windows 10

Model of modem, router, or other devices
==================
Fritz! Box 7490, Qualcomm Atheros AR9485 Wireless Network Adapter/Fritz Powerline Adapters and Motherboard: ASUS P8Z77-V

When the issue began
==================
3 or so Months ago

Recurring issue
==================
Yes

Description of problem
==================
Random Ping spikes occuring when using WLAN (which suddenly appeared a few Months ago) ranging from 150 to 500ms.Asked a friend who recommended switching to LAN (for which i bought Powerline Adapters). When using LAN the connection is just fine without spikes but then just stops working after a few hours and usually takes about half an hour to continue working. Nobody else in the house is experiencing these issues. And sometimes if i start up my PC, when i go to adapter options, it doesnt even recognize the ethernet adapter (it doesnt show up)

Cause/Steps to recreate the issue
==================
Use Internet

What I've tried so far to resolve the issue
==================
-Switching to a WLAN-USB-Stick, problem unchanged
-Switching to LAN; which only unearthed another Problem.
-Updating/Reinstalling all Drivers for the LAN and WLAN adapters
-Updating Bios (which fixed it for a short while but then after a week it just went back
-Reinstalling Windows
I think this is a problem with my Motherboard having parts slowly dying but im not sure...

Ping spikes are a typical problem when using wifi. It is caused by others utilizing the wireless network, or by interference from nearby wireless routers or other electronic devices. You can try changing the wireless channel on your router to find if ping improves, but this is usually only a temporary solution since other nearby access points automatically change channels to find the best frequency.

Your computer's wireless adapter is not capable of using the less crowded 5 GHz spectrum, which may help improve performance. You might consider replacing it, although this may not completely resolve the issue.

If low latency is important to you, I'd recommend having a look at getting a direct wired connection if at all possible.
