Ping spikes when playing CS:GO

Hey guys,

My friend has been having problems with his ping spiking up randomly on CS:GO during competitive matches (which is a huge problem because he's our carry haha). His ping is around 30ms, but it's been jumping to 70-250ms randomly. For example, when he rounds a corner he'd teleport back and have to round that same corner 2-5 more times to actually get around it, and he'd rubberband back and forth while walking in a straight path. Sometimes CS:GO freezes and the sound glitches, causing it to repeat over and over again for a few seconds.

We have tried reinstalling Windows 7 on the same HDD, using a different WiFi adapter, restarting the router and modem, reapplying thermal paste on the CPU, monitoring CPU temps under load (and they're fine). Speedtest is fine with a ~15ms ping, ~60Mbps download and ~10Mbps upload. Pingtest gives him a 21ms ping and a 2ms jitter (which should be fine as well.) An ethernet connection is not feasible because he's across the house from the router.

His specs:
CPU: AMD A4-5300
HSF: Stock AMD
RAM: Patriot 8GB DDR3-1600
MOBO: ASUS F2A55-MLK
HDD: WD 500GB 7200RPM
USB WiFi adapter: ASUS USB-AC53
GPU: Radeon HD 7480D integrated on the APU (he also has an nVidia GeForce 9500 GT which he took out to eliminate factors that could cause lag somehow)
PSU: Generic 250W that came with the case
Router: Motorola Surfboard SBG6580 cable modem + router combo

Any ideas?

Thanks.

There are other people on his connection, but they use very little bandwidth for reading the news and going on Facebook. He has also tried playing CS:GO when there is no one else and he still gets the ping spikes.

As for the background programs, we checked in Task Manager and the WiFi adapter gets about 5% usage max so we don't think there are other things using his connection. He closes every other application except TeamSpeak 3 for communication. This is on a clean Windows 7 installation as well.

Any other ideas?

Thanks a lot,

Well, although using an ethernet port is recommended for online gaming, in this case I suggest informing his ISP about the issue, and check the router too, there might be some problem with that.
and btw, Speedtest normally chooses the closest server to you for ping measurement. maybe choose a location closer to the CS server yourself?
