Archer AC1300 T4U V3 - 5GHz Ping Spikes & Instability
Hello,
I'm using Windows 10 x64 Version 1909 Build 18363.1110.
I have been having a lot of issues with the T4U having a lot of ping spikes every couple of seconds, making it perform terribly even in browsing tasks because every 10 seconds or so everything will freeze for a bit. As you can see from the picture the connection recovers itself without any user input after going down for 1-2 seconds every 5-10 seconds.
I have had the device for about a year now and I've always had this problem, even on the previous version of Windows (1893 I think). I used to use the 2.4GHz band before because I was far from the router anyway so it wasn't a big deal back then but now I've upgraded my home internet to 200Mbps, the router to an Archer C6 AC1200, and brought it closer so I need the 5GHz band to take advantage of the speeds.
I have browsed around a bit and noticed that a lot of people using the T3U are having the same issue and have gotten some special beta drivers that have helped. I've got a T4U which is different ; however, I tried those drivers to test anyway and unfortunately they didn't work. I still have the same issue using firmware versions 1030.38.0712.2019, 1030.29.1102.2017, and "Archer T3U_beta_U2_U3_5G unstable issue_1030.22.0202.2018" (same version as the official one but apparently a different beta driver) that were posted in other threads for the T3U. I have also tried connecting the device to USB 2.0 as suggested by some and that didn't help. Changing the wireless mode from Auto (2.4GHz & 5GHz) to 802.11ac (5GHz only) as suggested in other threads helped reduce the severity of the lag spikes a bit (from ~3500ms and timing out to ~1500-2000ms) but it did not help with the frequency (they still happen every 5-10 seconds) meaning that the device is still a terrible experience to use.
Are there any other drivers to try for the T4U or some other fix?
Thank you!
