Always spikes with Qualcomm Atheros AR938x Adapter, help?

Hello,
i'm hoping for some advice. I'm using wifi, and there are 10 other apartmens in the building. The building have three routers or so. I'm not sure which card I'm using, as it only says Qualcomm Atheros AR938x Adapter in the device manager, but I think it's a TP-LINK TL-WN951N 11n.

The last month i've been having issues spikes and it doesnt matter if its day or night. Typical ping in cmd is 9, 9, 13, 458, 234, 21, 9, 9, 500, 340, 30, 9, 9ms all the time. The speed is 30 down and 10 up in speedtests, and before it was completely fine with no lag, except when people were downloading a lot.

I've tried updating the network driver, turning off firewalls, connecting to other network (normal instead of 5ghz) but nothing seems to work.

However, I cant connect using a cable because the slots are taken, and the router is pretty far away from my apartment. And I. do not have access to the network settings. I've talked to my landlord, noone else seems to have this problem.

I should also mention that my laptop has lower ms with no spikes in cmd. I'm gonna try play a game or something and see if the network is better on it. But does anyone have advice regarding my computer?
Thank You

I didn't find the right solution from the Internet.
