Re: Packet Loss ONLY in Windows 10
SCROLL DOWN TO EDIT AT THE BOTTOM FOR UPDATE, STILL UNRESOLVED
I'm a bit late to the party but I see problem is unresolved.
I found a workaround but it's borderline stupid... but it works. I don't know what causes the issue but I've just spent a bunch of money on PCI-E WiFi cards as well as USB 3.0 AC adapters each to have same issue that's present ONLY in Windows 10 (coincidentaly all using Realtek chipsets) - packet loss or ping spikes (from average 18 to 3500 every few seconds) that otherwise are not present under Linux (in my case Mint) or Windows 7. I've also fiddled with power management to no avail. So it can't be faulty adapters, access points or other obstacle related problems. But you know what fixes the issue, temporarily? Installing this
Intel driver. Why temporarily? Because after restarting the PC problem is back again. So you have to run installer, pick repair and NOT restart at the end of the "repair". Bam, works like a charm.
About WiFi networks I'm trying to connect to. I'm sourcing internet from nearby hotel (with their permission) via Ubiquiti Loco M5 from over 100m (I've got direct line of sight with one of their access points). Ubiquiti is plugged into TP-Link router and that is broadcasting hotel's network in my apartment for all devices to use it. Packet loss or otherwise ping spikes are NOT present when connected via cable or via WiFi on non-Windows 10 hardware. Furthermore, standing in hotel's reception and connecting via WiFi with my Windows 10 machine I get packet loss, while both my smartphone and Linux tablet are experiencing no connection problems whatsoever.
So, my dear Windows Centrailsts - what the hell is going on here? There might be some processes conflicting or some services but I don't even know where to start and how to pinpoint actual issue. And why on earth Intel's WiFi driver temporarily fixes the situation on Realtek chipset?
Some of the adapters I still have on hand to further test this, all Realtek based (I've sent the rest back):
Alfa Network AWUS036AC USB 3.0
D-Link DWA-192 AC1900 USB 3.0
CSL PCI-E 300Mbps WiFi adapter
TP-LINK TL-WN851ND 300Mbps
In case of USB adapters which happen to be better and also feature 5GHz, problem exists on both 2.4GHz and 5GHz when using Realtek adapters on Windows 10.
My current PC that has problem only under Windows 10:
i7 5960X
Asus X99-E WS/3.1
64GB
1080Ti
edit:
I might be onto something. So a lag spike happens regularly every few seconds OR whenever I open up WiFi panel in system tray. After doing "intel driver fix" there are no latency spikes during normal use, however it spikes whenever I open WiFi panel in Windows 10 tray. Hence the conclusion that lag spike happens whenever system scans for nearby networks to "improve" connection. How to turn auto-scan off and have it only scan whenever I want to scan for networks? That would eliminate said problem, theoretically without resorting to "intel driver fix"
