Improved wireless range on cudy wr1300 v1 in future openwrt updates

Installing and Using OpenWrt
1

Hello OpenWrt Community,

I’ve been using different versions of OpenWrt on my Cudy WR1300 V1 router, but I’m experiencing a significant reduction in wireless range specially in 2.4GHz, compared to the stock firmware. Despite adjusting the transmit power, the performance remains suboptimal.

Details:

Router Model: Cudy WR1300 V1

OpenWrt Version: 24.10.0

Driver: mt76

Issue: The 2.4GHz wireless range is much weaker than with the stock firmware, and increasing the transmit power does not improve the range.

Request:

I kindly request the OpenWrt team to investigate this issue and consider improving 2.4GHz wireless performance on the Cudy WR1300 V1 (and similar devices) in future updates. Any fixes or optimizations for better range would be greatly appreciated.

Thank you for your time and consideration!

Best regards,
Zayed

First check you have set country code, set it if not and post outputs of

ubus call system board
cat /etc/config/wireless # empty mac addresses and security keys and ap names

from ssh (like putty) session.

i have set the country code to bolivia and also tried others method. I think the problem is in the driver. its not optimized for this router model.

You have to set real country code, especially with other people in range. In addition to requested files please show channel map in 2.4ghz band from iw list
With standard 20dBm world domain signal indicator should weaken at 15-20m and disappear at 40-50m distance.

i have also tried with my real country code, it didn't work. after commanding iw list in the putty it shows:

So OEM firmware ran out of specification. I described 20dBm range.

what do you mean? I want to get the maximum range as OEM firmware. what is causing this problem after installing openwrt?

8

Hard to piece it together if you do not provide conf files.

9

which specific conf files should i provide? Let me know exactly what you need.

This parameter is not from OpenWRT. Did you restore OEM backup or something?

Basically both txpower parameters LIMIT wifi signal.

I would suggest to reset the device and start fresh
1/ set wifi country
2/ set wifi security (same in both bands)
3/ set channels auto
4/ enable wifi

13

i have installed openwrt using cudy website provided firmware file:

then i have switched to letest 24.10.0 version using systemupgrades. I have tried all the methods before that you have suggested. i have switched to stock firmware multiple time and got better range in the stock firmware. the problem must be in the openwrt firmware. i think it's driver problem. it's not fully optimized for the exact hardware of my router. If you are in the openwrt team can you please tell the higher officials to solve this problem on next version releases?

14

There is a strange parameter combination in your file. Try to create simplest setup imaginable without clicking in all other places. It says 20dBm which means <15m ideal reception >50m none
"driver default" setting means "maximum permissible with hardware and regulatory combination"

You did your install correctly.

16

nonono, OP upgraded to proper 24.10.0 after, everything is fine, version tags confirm proper installation.

17

Ah...ok...

in that case, I agree with the previous advice that the OP should reset to defaults and only change the bare minimums.
