Missing 5GHz wifi on R7500v2

Hi all!
i installed with success OpenWRT latest (19.07.3) on my Netgear R7500v2.

It is amazing, first time user of OpenWRT and i LOVE it.

One problem, there seems to be no 5Ghz radio. I can see only "radio0" under network/wireless and it says it's 2.4Ghz...

What sould i try?
It seems to be supported (only the r7500v1 has no support for 5Ghz on OpenWRT...)

The R7500v2 should be fully supported, check dmesg for potential hints.

I might take exception to the "fully" adjective... but ya, 5 GHz works pretty well on my r7500v2.

I just fell down the board-2.bin/firmware rabbit hole after finding qca-swiss-army-knife. I'm trying to make my way out.

@gardiol in case you are unfamiliar, "dmesg" is the kernel log. You should be able to view & copy it from luci by looking under the "Status" menu, "Kernel Log" item. If your comfortable logging into you router via ssh and using the command line, then just type dmesg.

You can post the output here using the Preformatted text item but please check that you do not post information you may not be comfortable sharing such as ip address or mac address.

I've been running "snapshot" images and I actually haven't tried any of the stable 19 versions. Perhaps there is an issue that hasn't been noticed before. BTW the latest is 19.07.4 but that just came out a few days ago.

Here is the "dmsg". I am quite fmailiar with linux and such, just newbie to OpenWRT...

Excellent, but I think I may have bad news. From the dmesg this looks like a R7500v1 (or maybe the firmware loaded on it is the r7500v1?). I'm not an expert on this so definitely seek a second opinion. Here is what I see from the dmesg:

OF: fdt: Machine model: Netgear Nighthawk X4 R7500

mine will actually say "R7500v2" (a dmesg from my device is here but this is using a snapshot image i.e. not 19.07.4)

Also the wireless reports in the dmesg as a 988x here:

[   12.036796] ath10k_pci 0001:01:00.0: qca988x hw2.0 target 0x4100016c chip_id 0x043202ff sub 0000:0000

My r7500v2 uses the 9980 driver/firmware for both 2.4 and 5 GHz wireless (the openwrt wiki and wikidevi say that the v2 has a 9880 but I think that's wrong - I actually remove the 988x driver/firmware and both wifi bands work fine for me.)

If you are certain your unit is a r7500v2, double check you actually loaded the r7500v2 image. If you suspect its actually a r7500v1 you can try the v1 image. I suppose the v2 image comes with the 988x wifi driver/firmware in case of situations like this...

Did you get this device second hand?

I am pretty sure i flashed the v2 firmware because the v1 firmware did not flashed correctly...

I bought this device as new a couple of years ago on Amazon... Always had issues with wifi, so i decided to flash OpenWRT and give it a try. Flashed the image from the NEtgear web gui and bricked it. Then i followed the guied to unbrick by the mrpflash tool... but it did not worked with the v1 image, while it worked at the first try with the v2 image....

How can i actually find if i have a v1 or v2?
At this point it seems more a v1 even if i flashed the v2 image...

By the way, what is a good and cheap device which support mesh? That is something i would like to try with openwrt!

From the kernel log, it looks like a v1. As I don't have a v1 and there is was a warning in the openwrt wiki about flashing a v1 without a serial console, (at least initially when coming from something other than openwrt), I'm hesitant to advise you here. I've seen others post about the v1 so maybe search the forums and see if an existing user is willing to advise you here.

EDIT: it seems the warning about using a serial console has been removed (others have speculated that this warning may be overblown - use your own judgment)

If it is a v1, I don't think you are going to get 5 GHz using openwrt regardless of what you do.

Only if you can afford to replace it and live without it:

I might try flashing netgear_r7500-squashfs-factory.img (a v1) image via tftp and see if that works and if the dmesg is any different. You can also try flashing a v1 "sysupgrade" image via luci web interface but that might be more risky.

After that I might then try flashing netgear_r7500v2-squashfs-factory.img via tftp.

If your unit is actually a v2 and it turns out you accidentally flashed a v1 image from the start, I'm pretty sure you have nothing to worry about. My experience (and others with r7800's - similar to the r7500v2) is that it is really hard to break it by tftp (or luci web interface) flashing the wrong thing.

If it turns out to be a v1, its still a great switch and a decent router. Only having 2.4 GHz would be a disappointment.

Lastly, I don't use mesh so you might search the forums and then open another post about that.

Thank you...
As soon as i will have time i will try.

I remeber trying to flash the v1 firmware without success twice. One from the netgear GUI and one from mprflash. While the v2 just worked. Also, i downloaded the v1 image twice to be sure. anyway, i just bought a Netgear R6220 which seems to be perfectly supported (and at an amazing pricepoint) so as soon as i get it, i will set it up instead of the R7500, so i can start playing with it without losing wifi. If all goes well, i will have two OpenWRT routers and start playing with mesh stuff. If things goes bad, i have back 5Ghz on the R6220 and that will fit the bill anyway.

A pity for the R7500, but it never worked well for me anyway, it might be defective on the wifi part who knows. with OEM firmware i had to reboot it weekly or i would randomly lose WiFi connection.

The FCC ID should provide some clarity (so would taking a peek at the PCB and comparing it to the FCC images).

Sorry for the delay! I finally solved the mistery, and i have a R7500v1, not the v2.

I tried to flash the v2 image and the router will not boot. So i flashed again the v1 image and the router booted fine. At this point, i am pretty sure it's a v1. Quite sad, i did pay a lot for the router a few years ago, and it sucks, but hey, it's the way it is. Still a great 2.4g router.

Thank you all!

Sorry to here that but I'm glad you worked it out. For the benefit of others that might read this thread, should mark your post above as the one that "solved" it.
