Unifi network question

father-ted · 22 May 2021 at 10:07

Hi,

I have x3 unifi standalone access points, all using the exact same settings and channels.
I have noticed that the 5g can sometimes show issues, I am thinking it could be channel congestion clashing with neighbours etc.

I have used a wifi scanner from my phone.
My 5g is using channel 48.
What are the higher DFS channels, should I be using those instead?

Or, should I set all channels on all AP's to 'auto' and let it do its own thing?

Thanks

I don't think you have anything to lose by setting them to auto, you certainly do not want them set to the same channel thats for sure.

Ok thanks, will give that a try

I presumed that they all needed to be on the same channels for seamless movement from AP to AP when moving around the house

Out of interest, am I better designating each channel per AP?
On auto on them all, I notice some are using the same channel.

100% don’t leave them on Auto. On 5GHz I very much doubt that the neighbours WLAN is giving you serious interference.

If you have all your APs on the same channels then you are generating your own interference!

I’ve been criticised in the past for telling people to fix channels without seeing the spectrum in the area but just put one on 36, one on 40 and one on 44 or 48. I bet it’ll work pretty well. Don’t go up into the DFS channels because if radar is detected near your house they’ll shut down.

On 2.4GHz, put them on channels 1, 6 and 11.

Ok thanks.
I have sky using up channel 36, so have gone for 40/44/48 on the 5g.
All tests working fine so far, firesticks working much quicker as well.
They were getting around 40mb download previously - now getting 160-170 :-)

OK, what is VHT set to? Even on the cheapest units you should be able to set VHT40, which will give you a boost over VHT20 as standard.

VHT? Sorry I am a noob at this.
Do you mean the bandwidth? If yes, I have it set at 40 (not 20) - 2g
80 on 5g

Make it 20 on 2.4GHz, there is only three non overlapping channels that adhere to the common usage that supports 802.11b devices.

ok thanks, done that

I was under the impression that Ofcom had removed Dynamic Frequency Selection (DFS) requirements from channels used by Wi-Fi in the 5.8 GHz band (5725-5850 MHz).

i.e. 149 - 165

a 80Mhz width of 80 on channel 155 should give very good performance, but some (not that older) devises may not be able to connect to it.

Summary of our final decisions

6.1
In conclusion, we have made the following decisions

a)To permit licence-exempt RLAN use, including Wi-Fi, in the lower 6 GHz band (5925-6425MHz).Indoor useup to 250mW and outdoor use up to 25mW will be permitted; and

b)To remove DFS requirements for the 5.8 GHz band (5725-5850MHz), for low-power (up to 200mW) indoor Wi-Fi use only.

6.2 These bands will be made available on a licence-exempt (non-protected and non-interference) basis with technical parameters that provideadequate protection forother users.The technical conditions are technology neutralso, as well as Wi-Fi, we expect other similar RLAN technologies, such as licence-exempt technologies based on 3GPP standards, to be able to access the spectrum we are making available.
