I've installed OpenWrt 18.06.1, r7258-5eb055306f on a Linksys WRT3200ACM. Setting up the 2,4GHu Wifi using the radio1 controller (listed as "Marvell 88W8964 802.11bgn") was no problem (I can connect to it and the according LED is on) but I was not able to do the same for the 5GHz Wifi controller(s).
1st question: As far as I understood I have to use one of the additional controllers:
radio: Marvell 88W8964 802.11nac
radio2: Marvell 88W8887 802.11bgnac
Which one I should use?
2nd question: My first tries end up with "Wireless is not associated" problem so I tried to set " radio2" with
Channel: 60 (5300 MHz)
Width: 80MHz
SSID: mywifi_5G
Unfortunately neither the 5 GHz LED is on nor can I see "mywifi_5G" in the list of available Wifis on my PC.
The wifi driver in the release build is (by now) quite old and not very mature which is most likely what you're seeing.The one in master branch (trunk) is much more stable and reliable.
Radio0 is the 5ghz radio (that you have disabled),
radio1 is the 2.4 GHz
radio2 is the crappy 88w8887 without antenna, and it should not be used. It is originally meant for radar detection or something, but not for actual use.
I think @hnyman may have answered my problem. I have no prior experience whatsoever with flash routers but now need such technology for a variety of reasons.
In short i have been reading, studying like crazy before installing on my WRT3200ACM today with help of a Linksys technican this build:
Radio 2 giving me the same issues: either not associated and no signal when associated. I will delete Access Points for Radio and create them using Radio 0. I sincerely hope this handles my problem as I am now currently unable to reconnect a range of devices to wifi until I get this solved.
I created my first access point while the router was hardwired to my laptop and it appears to be now a part of my default lan, wan configurations. The laptop seem to have a DHCP server function:
[removed printscreen showing mac addresses, etc. probably wasn't a good idea in the first place]
If the above prtscreen displays (having used cut-paste, I would appreciate feedback. If this is a legitimate problem, it may require a seperate thread as I haven't been able to find one. (experienced users, Please advise. I don't want to waste anyones time)
