So far everything is going well, but unfortunately I have problems with the radio module. The device usually has 3 different frequency bands (SSIDs) and supports 1x 2.4GHz and 2x 5GHz at the same time:
SSID1 (2.4GHz): WAVLINK-N
SSID2 (5GHz): WAVLINK-AC
SSID3 (5GHz): WAVLINK-AC-1733M
LuCI only shows 2 radio modules under /network/wireless (radio0, radio1). radio0 should support the 2.4GHz band and radio1 the 5GHz band. So far so good.
Now I would like to set up an SSID for radio0 and radio1 each. I named them like this:
radio0: OpenWrt_TEST_N
radio1: OpenWrt_TEST_AC
If I want to set up another, second SSID for radio1 (OpenWrt_TEST_AC1733), the 5GHz radio module no longer starts and hangs up. After restarting the router, I no longer have access to the shell and LuCI, and a connection is no longer possible to configure the router. I have to reset it.
I adjusted the radio channels in the same way as with the OEM firmware. With radio0 it worked without any problems, but not with radio1. If it worked, both SSIDs (OpenWrt_TEST_AC / OpenWrt_TEST_AC1733) were broadcasting on the same channel. The channels are and should be different from the factory.
Did I do something wrong? Why do I only see 2 radio modules? Is the driver for this router possibly incompatible because I worked according to the instructions for the WS-WN536A8? But according to these instructions, the same hardware should be installed.
It's not yet an officially supported model, so you're using a third-party build and you should seek support from them. This forum is for builds obtained from downloads.openwrt.org or built yourself from the source code.
It looks like there should be three radios. With most drivers, two SSIDs on the same radio is readily possible but of course it doesn't gain any bandwidth. It is useful to connect different networks such as trusted users and guests.
And I sort of have figured it out. The trick was to disable the frequency limit on one of the radios, since one of them is responsible for both the 2.4 and 5 GHz band. I started with the most similar supported thing I found: wavlink wl-wn531a6, and changed:
I had a following issue with the power of the radios, which got limited at 7 dBm, but then hacked the code to enable larger powers. Let me know if you find the same thing. Probably what's really missing is some eeprom info, but I haven't figured that out yet.
they're in the source, but I think it's possible to extract them from an already build image, if I remember correctly. There was a thread or two about it recently ...
This thing drove me crazy with it's crap stock firmware, was so glad to get openwrt on it in any semi-working condition. That said, I don't know if this will help but I dumped a gist here:
Mostly all of the info I could source at the time a while back; from other folks efforts to reverse and dump these wavlink / winstars / jetstream / Ematic AC3000 triband routers.
could resolve the 5GHZ radio2 patching issue. I personally never attempted.. There are only 2 physical removable mpcie modules in this device (daughter cards?), one for 2.5ghz and other for 5ghz.
Other thoughts would be reversing this original firmware file might yield some light(tpd)
on the issue.
Possibly dig source, and it's logs within and see how they solve patching the modules in. Thinking they originally used openwrt as a base imagebuild anyhow to make their shitty * Lighttpd webserver web server ontop of anyhow..
Could always check out binwalk or ... some of the firmware tools from this virtual machine that easily loads firmadyne on a buntu machine in virtualbox.. here. https://github.com/adi0x90/attifyos
At this point however, just getting it dirty flashed with almost everything else out of box working in openwrt was way way better than stock firmwares shortcommings. GJ Walmart
Seems to affects EMATIC JETSTREAM WINSTARS WAVLINK devices. Just another reason to get these devices flashed with actual openwrt and far away from the stock firmware it ships with.
