1convert wan to lan 2wwan connection drops 3slower wifi speed/good wired ALFA R36 WR6202-1U

Installing and Using OpenWrt
1

i tried lots of setup option concerning the switch topology to convert the r36 wan to lan so i can use 2 wired connections since i use it as an extender with wireless wan.

The alfa r36 has the board of wr6202-1u (mips32 24ke rt3050F) not the w502u if there actually are differences that are notable i hesitate. the w502u images also work on my device.

Currently use LEDE Reboot 17.01.0 r3205-59508e3 stable release.
the additional packages i installed are minimum for basic functionality:
*kmod-nls-base
*kmod-rtl8187
*kmod-usb2
*kmod-usb-core
*kmod-dusb-dwc2

as the rtl8187 (alfa awus036H) is functioning as a wwan

1)the goal im trying to achieve is firstly convert my my wan port into a lan port so the device ends up having 2 functional lan ports.
2)stop wireless wan from dropping which only gets fixed with a reboot (not inid.d/network restart)
3)tried everything to make wifi fast every possible setting including many beacon intervals on both client and access point (since its an extender)

literally everything possible from the config. what is weird is im not in a crowded area whatsoever whenever i do manage to get it working quite decent through wireless it has a certain delay to reach almost near peak connection while still fluctuating which isnt a lot btw

from the wwan i have about 4/5 mbit on a wired connection even in ht40 wmm on various channels including 13 since its legal in my area wlan fluctuates 1 mbit 2 mbit 3 max

currently i removed almost every option in wireless settings since it did not matter much
i like to note that the client 8187 uses a 2.4Ghz parabolic grid 24dbi and the access point a 9dbi omni, the router also has a decent heatsink as an extra so does the rtl8187 chip because they run constant sometimes with higher temperatures.

I would sincerely appreciate any possible help or suggestions on possible improvements on either 1 of the 3 issues i am dealing with since i have spent countless hours in playing around with every possibility im also interested in what people deal with while having the same device

some additional info to the above, forgot to mention that the drops in wifi arent drops from the local wlan neither any drop physically.
both wlan and wwan stay connected after having applied my settings, the drops are not anymore time related however with continuous usage if it is intense the internet connection drops while both wwan and wlan stay connected.
over wifi i also have the issue of a certain delay before the peak of speed is reached and after fluctuates, something which is not present on a wired connection which works perfect despite of it functioning as a wifi extender

i also have tried it with several awus036h with same result so it isnt a hardware malfunction.
also with the awus036nhr v2 (8188RU) and the awus036nhv csv (8188EU) but overal regardless of lack of N support the 8187 seems to be the most robust.

real drops i only had with openwrt chaos calmer but not on lede anymore.

furthermore i like to note that the original lan is fully functioning it is just the converted wan to lan port which remains undetected by any device and does not provide dhcp.

since every device has its own topology i tried following the correct guide for the r36 however wan is still not functioning as lan.

next to all the last issue im having is when one device starts using significant bandwith other devices sometimes dont operate anymore, tried installing and configuring QoS but without any significant effect.

i believe this description captured all of my lasting issues that i haven't been able to fix.

maybe this is the reason it isnt working while it should ( wan to lan port ) https://patchwork.ozlabs.org/patch/561991/ anyone?

Can you get the awus036hnv to work with openwrt?
What driver did you use?
I can't get mine to work

user just posted here: 8188eu drivers

Please don't hijack posts.

Hello,

I hope this isn't 'hijacking' a post. I have an 8188RU chip on USB and can't fathom which driver package and version to use with it.

Did the OP get his 8188RU working?

Many thanks.

ive ditched this setup long ago because of its hardware limitations however if i remember correctly i had managed getting all to work. if you still have this device im guessing it will work way better with latest wrt updates and newer kernel. i dont know how firmware is compiled by buildbots but this device definitely needs to have firmware compiled with -0s to save some space. and because its a while ago the only thing i do remember is the 8192 drivers i might have used for the NHRv2. i didnt understand the concept of load balancing when opening this thread... let me know if it solved your issue. i guess install every driver and check which gets loaded and keep it. to save you efforts 8187 8188xx drivers and 8192. btw off topic this router works very well with 9dbi antennas the range it gave is ridiculous. sorry for the late response, didnt log in and didnt bother that much updating for a period. you probably already know this but i suggest the very least once you figure out the drivers and setup include all in https://firmware-selector.openwrt.org/ and let it build. use attendedsysupgrade after because of the space issues. just in case for newer members reading this that go off installing everything separately and the way squashfs works preventing it from running out of space and freezing. i dont have the chip laying around but in case of the RU i think it definitely worked. ive used an RU NHR and NHV back then so thats why the confusion. if you still cant get it to work i might hook it up and update it and check whats going on to refresh my memory but for convenience sake of new members finding answers i suggest a new topic.
