Dear all,
I have the following problem:
- Unreliable connection and many time-outs/data errors, even while surfing
- I narrowed it down to a latency issue: pinging my WiFi-router, the ping is between 3-10 ms, but every 10th attempt or so (no constant) is a ping over 2000 ms or a time-out. In every series of 30 pings there are 3-4 extreme spikes.
What I've tried:
- Update drivers in Windows 10 with manufacturer's drivers. No change.
- Change router channel. No change.
- Change location of the PC within the room. No change.
- Change USB WiFi dongle. The problem remains is the same, with two different D-Link DWA-172 and a TP-Link WN723N. All three work fine (no ping spikes) on another PC in the same room and on a laptop directly next to the PC in question.
- Change USB-slots. No change.
- Change b/g/n-protocol to b/g-only in the driver settings under Windows. That reduces the 2k+ ms spikes to c. 500 ms, which is still a lot.
- Do the ping-test on a live-Linux-system. No change.
So I figured, that the latency issue should be related to the USB-controller (on-board GIGABYTE GA-Z68M-D2H). A BIOS update didn't produce any change. Another PC with the same chipset, the same dongle and the same OS does not have the problem. Also, I have a USB-mouse/keyboard-dongle running on the same system without any lags. I am really running out of ideas here. Any suggestions anybody? Thanks a lot!
