Hi, So the problem is basically my WiFi speed whilst streaming games, video and torrents if fluctuating.

So far I have tested it with a LAN cable and I have no problems, plus I have other computers connected as well over WiFi and then tested the same games with no problems.

The problem is not a 100% repeatable but it also has problems making the connection first time, after a few attempts it connects and something the connection can pick after a few minutes of lag.

This problem does not happen on other laptops and seems unnoticeable over a LAN connection.

I have deleted all the drivers and reinstalled them. It helped for some time and then the problem came back.

I have a Killer Wireless N 1202 card and driver.

Operating System:
Windows 7 Professional 64-bit SP1
CPU:
Intel Core i7 @ 2.90GHz
Haswell 22nm Technology
RAM:
16.0GB Dual-Channel DDR3 @ 798MHz (9-9-9-27)
Motherboard:
Notebook W65_67SJ (SOCKET 0)
Graphics:
Generic PnP Monitor (1920x1080@60Hz)
Intel HD Graphics 4600 (CLEVO/KAPOK Computer)
2047MB NVIDIA GeForce GTX 850M (CLEVO/KAPOK Computer)
Storage:
447GB KINGSTON SMS200S3480G SCSI Disk Device (SSD)
698GB Western Digital WDC WD7500BPKX-00HPJ SCSI Disk Device (SATA)
Optical Drives:
TSSTcorp BDDVDW SN-506BB SCSI CdRom Device
Audio:
VIA HD Audio

I have run out of ideas?

Thank you guys.
