I was requested to re-submit my issue here on the wireless forums regarding high latency in games for the Intel Dual Band AC 7260 wireless adapter. It came from the OEM in my Lenovo Y50 laptop (not installed by myself). I've tried many things in attempts to diagnose and resolve the issue including:
- Resetting the router
- Testing multiple games to ensure the latency issue is not within just CS:GO
- Plugged in an external adapter (Belkin N300 USB Wireless NIC), this produced better more stable results
- Added "ScanWhenAssociated" to the registry (previous known fix for high latency)
- Ensured all as many bandwidth eating features in Windows 10 were off such as One Drive Sync, Xbox Streaming Service, Shared P2P updates, etc.
And just a couple hours ago, wiped the entire SSHD in the laptop and did a completely fresh install of Windows 10 Home Edition 64Bit.
After the fresh install, the issue 'appears' to be less predominant, but then again, the time of day is 1:30AM and if the issue is lying within interference, it would be coincidental that
my findings on the pre-installed (during Windows 10 installation) driver 22.214.171.124 would not have my ping in CS:GO reach over 70 (perfectly acceptable).
I then proceeded to install the latest driver from Intel's download page (126.96.36.199), when hopping back in game, latency started at 130ms, settled down to around 55ms in about 10seconds and frequently would bounce
between 55-85ms throughout the match with three notable spikes to 130ms over the course of a 25min game.
Since i've done a fresh install, I don't yet have any other games to test at the moment.
Side notes that may help:
- This NIC has given trouble in the past 2-3months after purchasing the laptop. Using the OEM's driver, it suddenly started dropping connections and completely refusing out right to connect to my university network.
- The machine ran Windows 8.1 Pro 64Bit installed by the OEM.
- I went through 6-7 different drivers before resolving the issue by installing 188.8.131.52 which was the 'perfect' driver. No more dropped connections, no high latency. This was all on Windows 8.1, and i proceeded using the machine like this for almost a year till now when I had windows update upgrade my 8.1 installation to Win10 home edition.
- The issue occurs even with only one other connected to the AP. My phone, which is not being actively used
- My ISP, router, etc.. Have not changed since when I had stable performance with this NIC on Windows 8.1
- I attempted to use Windows latest driver, Intel's latest driver, and Lenovo's latest driver for the NIC on Windows 10. None helped.
If there are any tweaks/settings I can change within the adapter or another driver I can try installing, please let me know. Wireless is currently the only means im able to play any game online at the moment.
Everything was stable on Windows 8.1 and I really hope we can get things working right with Windows 10 too! I know im not alone on this issue as I've been responded to on Steam discussion forums regarding the exact same problem. Some incite on what is causing this issue and how to go about resolving it is much appreciated!
Thank you for giving this a read.
