Archer C7, Extremely Slow Wireless Speeds

Installing and Using OpenWrt Network and Wireless Configuration
1

TP-Link Archer C7 v5, OpenWrt 19.07.3 r11063-85e04e9f46 / LuCI openwrt-19.07 branch git-20.182.58453-b573f10

Just moved and got gigabit, over ethernet I am varying 400-700mbps which seems overly large, but not sure. My bigger concern being, my wireless seems to be painfully slow in comparison, running from 10mbps to 50mbps. Tested on multiple devices, and seems to be the same on both 2.4ghz and 5ghz. I still don't have my setup completely configured and am a little confused all around due to moving and resetting things up so I could be missing something stupid or need to change something.
I could be wrong, but I don't recall getting these speeds at my previous place, well I paid for 100mbps there, but I recall I always consistently got at least 40mbps at my previous place.

I notice on my devices, it shows my link speed here is only at 100mbps. Not sure what's going on.

I've tried changing channels, and I did enable software offloading.
I used to have SQM enabled, but tried disabling for now just to see if that was affecting it.

This is my /etc/config/network file:

config interface 'loopback'

        option proto 'static'
        option ipaddr '127.0.0.1'

        option reqprefix 'auto'
       option reqaddress 'try'
        option peerdns '0'

        option vlan '2'
        option ports '1 0t'

If you need any other files lmk.

I had the same, you have to enable software flow offloading and hardware flow offloading at the firewall tab, it fixed mine.
It was very bad before.

3

Ah, I only had software flow offloading enabled, didn't realize it created a new box after enabling.

However, my speeds do not seem to have increased at all on wireless. :confused:

4

What channel? Do you have others on the same channel? Try DFS channels. I have a lot of CoxWiFi signals near me so even my 5GHz is crowded so I use channel 112.

5

Did you try a different driver. See -- Archer C7 2.4 GHz wireless dies in 24~48 hours

6

As I stated I tried a few different channels on my 2.4Ghz, although I also have far less signals around me where I am now then where I was before.

7

Did you try a different driver

I have not. Looking at that link, they are discussing Archer c7 Revision 2, I am using Revision 5.

opkg remove ath10k-firmware-qca988x-ct kmod-ath10k-ct ath10k-firmware-qca988x-ct-full-htt opkg install ath10k-firmware-qca988x kmod-ath10k

Is that all I have to do? And again, are these the correct packages to remove and install for revision 5?
The drivers I see installed are as follows:

ath10k-firmware-qca988x-ct kmod-ath kmod-ath10k-ct kmod-ath9k kmod-ath9k-common kmod-phy-ath79-usb

In the event that these do not do anything, break, or make things worse, how do I revert?
Do I just reinstall the packages I removed? I've noticed OpenWRT backups and restores (Through LuCI) don't seem to install/remove packages, only settings.

8

Try 5 GHz. 2.4 even with like 3 other signals can be crowded.

That didn't seem to do much.
