Here's my sad story: I've been having lots of problems with my connection, i get lots of lag spikes, failed pings etc. My laptop has allegedly a bad wireless card (acer aspire nitro v15 black edition) and I also have 2 wireless repeaters plugged into the walls. I tried every possible setting on the router and the 2 repeaters with no success, so I thought it had to be the laptop itself. I bought a usb wireless adapter from Hamlet (a pretty standard one) and my connection has been good for many hours, but for some reason after 2-3 hours i get huge latency every 10 seconds, like ping jumps from 60 to 1900 every 10 seconds or so( even if I ping 192.168.1.1).
The strange thing is that if I use my phone to ping I get no spikes, always a perfect 50ms latency!
I really don't know what to do, as it's neither a network problem nor a hardware problem, since i'm getting these lag spikes on both the internal and external wireless card. Obviously i disabled the internal card since I'm using the usb one now. What could it be? Some strange Windows problem? I don't think I have any viruses, or programs that use bandwith in the background ( and even if I had I should get the same lag on the phone too, right?) So please help me. Thanks in advance.

P.S. Yes, the driver is updated, i have no special settings in the wireless card ipv4 options ( no custom dns or such), neighbours' wifi is on a different channel.

Router model: N600 Wireless Dual Band Gigabit ADSL2+ Modem Router
Model No. TD-W8980

Wireless extenders: 300M Wireless N Range Extender
Model No. TL-WA850RE

External usb wifi adapter: Hamlet wi-fi 300n Nano USB adapter HNWU300NN

EDIT: i unplugged all the repeater and connected the laptop to the main router from a distance of 1 meter and i still get the spikes, so it's not a repeater issue.
 
Solution
if you have virus or malware on the pc that wont affect the phone connection since they are 2 separate operating system so do a malware scan and full virus scan without network also check if you dont have any software that are on auto update and check net all the time .
