hi,

does the pi3 b+ support 5ghz wifi?

i have a feeling it doesn’t but i cannot find a message in 8fans passim which states one way of the other,

i understand it will probably be no quicker but i am seeing miserable performance from wifi at the moment which i am fairly sure is due to my neighbours on the 2.4ghz band. 5ghz on the other hand looks fairly free.

on the same topic - is 5ghz supported on the pi4 ?

-Steve

Yes to both - as regards the hardware.

I can't recall whether the ether4330 driver tries
to connect to 5ghz channels. You could experiment
by giving your router a separate 5ghz-only SSID
and see if you can connect to that.

I was trying to do just that last night on a very old pi3b+ and it seemed
to choke on

aux/wpa -2p -s SSID_5G /net/ether1

It was way past my bedtime so I quickly gave up and connected to a 2.4GHz
SSID instead.

Did you bind '#l1' first?

Here's what works for me:

term% bind -a '#l1' /net
term% aux/wpa -2p -s 1d2e12-5GHz /net/ether1

!Adding key: essid=1d2e12-5GHz proto=wpapsk
password: 
term% ip/ipconfig ether /net/ether1
term% cat /net/ipselftab
term% ip/ping 9p.io
sending 32 64 byte messages 1000 ms apart to icmp!9p.io!1
0: rtt 32638 µs, avg rtt 32638 µs, ttl = 246
1: rtt 29566 µs, avg rtt 31102 µs, ttl = 246
...

Yes, I did.  Basically followed the same instructions as you wrote
below (think I even took them from your reply on an older thread
so thanks!) plus 'ndb/dns -r'.  Worked for 2.4GHz but not for 5GHz.
A quick internet search suggests a possibility that the 5GHz band may
need to be enabled by setting the regulatory domain/region.  Will give it
another try at some point; a bit hesitant right now since it's a normally
headless setup and I don't want to mess with connectivity too often.

I stand corrected.  There was a mix-up with an older 3b, which only
has 2.4GHz (too many rpis lying around).  Sorry about the confusion.
