Been following DD-WRT for a while now. I have both WRT3200 and WRT32X routers. During that time, I have run both DD-WRT and OpenWRT. Post DD-WRT 44048 releases do not work reliably for me, due to wireless issues, so I reverted to OpenWRT 19.07.4 (released on 10 September 2020). Results have been positive. Both my wife and I have been working from home for the past 6 months, so reliability is paramount. Waiting for positive reviews on a future DD-WRT release.
I have the same experience using a wrt1900ac v1. ipad/iphone/laptop all behave the same with both 2.4 and 5GHz. I have tried tinkering with all the settings and the only fix iis to disable wmm support. This obviously cripples the speed but it seems to be working okay.
Did a clean upgrade on WRT3200ACM, everything I use is working with sound settings, so far a good build for about 4 days.
Anyone having WiFi issues should probably leave in mixed mode and have sane frequency settings for the country with automatic channels as well.
Will update if there's any issues. _________________ Router: Linksys WRT3200ACM

I tried to use all the channels available for my country and I also used the auto mode, the results were the same.
I did the installation directly from the interface of the original Linksys software after I made sure to put on both partitions firmwar from Linksys, DD-Wrt is written on partition two.
Usually on OpenWrt I write directly from the Linksys software,the latest version available, which is I leave it installed on the first partition!
Even when it comes to an update, I prefer to come back with a clean writing of software again! _________________ Internet provider https://en.wikipedia.org/wiki/RCS_%26_RDS RCS & RDS 1Gbps

On the ETHERNET side things move very well, it runs without problems 1Gbps,in the speed test it has a value somewhere at 934 Mbps..
A little clarification I want to make, on the 5Ghz wifi side I can no longer reach a speed higher than 470Mbps in download, even on 2 Ghz the speed decreased, the rest of the settings are default... As a recommendation, on the wifi side you better go back to this drive version 06-15-2020-r43420 #1, in this wifi version it is stable and good speeds in speed test!
I also encountered this problem in OpenWrt since they came up with the last three changes in the wifi driver... All devices have connected to wifi, so far everything is ok and I want to add that ipv6 is stable and if changes are made in some tabs it continues to be active and most importantly the web interface is stable!
For 80Mhz width, either you pick channel 36 or pick 149. Otherwise it is considered overlapping or using DFS channels that could be not allowed or mess with the channel busy time. For 40Mhz you have more non-overlapping channels. For 160Mhz just the 149, but you don't want to use that unless you're connecting two capable routers to eachother. Trust me, I've been fighting with wireless channels for so long. _________________ Linksys WRT3200ACM

fwiw I've been using channel VHT 160, AC/N mixed, and channel 100 + 14, and I put the power to 23db instead of the default 20.
So far this seems to be the only method or way I've seen to be able to get the full 940mbps download and 920mbps upload speeds that I pay for. My 9th gen intel processor and z390 chipset motherboard connects at 1733mbps and although my speed test speeds always fluctuate, I seem to pull the best results using the channel 100 / vht160 / ac+n mixed mode combo.
Also, this mode is config is the only one I've come across so far where I can get 600mbps download and almost 600mbps upload on my iPhone XS 512mb running iOS v14.1.
Anyone else have any luck or experience with using just VHT 80 for the 5ghz and able to hit 600mbps download/upload on an iphone 8/X/XS/11? Or 900+mbps down/up wirelessly from a desktop computer?
