I am attempting (so far without sucess) to set up two WiFi domain with WDS.
The hardware I have to hand are a pair of BT Home Hub 5A. Both have OpenWrt 19.07.4.
If I issue iw list command, I get this (abridged) output:
root@OpenWrt3:~# iw list
max # scan SSIDs: 4
max scan IEs length: 2257 bytes
max # sched scan SSIDs: 0
max # match sets: 0
max # scan plans: 1
max scan plan interval: -1
max scan plan iterations: 0
Retry short limit: 7
Retry long limit: 4
Coverage class: 0 (up to 0m)
Device supports AP-side u-APSD.
Device supports T-DLS.
Available Antennas: TX 0x3 RX 0x3
Configured Antennas: TX 0x3 RX 0x3
Supported interface modes:
* mesh point
* outside context of a BSS
SM Power Save disabled
... output truncated here...
... is this a show-stopper (no WDS in the "Supported interface mode")?
Do you mean the WiKi I pointed to in the opening post? If so - yes. But fell at the first hurdle!
But If I were to try again, how should I implement these instructions?
Main Heading: SSH
Sub Heading: The Access Point
Once logged in, edit the /etc/config/wireless file. In the existing wifi-iface section that is being used, add a line with option wds '1'.
Note that there may be multiple wifi-iface sections in this file, especially if the router is a dual band device, in which case **you need to ensure that you're editing the correct section**.
Considering that this is my /etc/config/wireless contents:
Yes, I have been trying (for the last two days!). This is what I have been doing. The bullets are from the wiki..
For the wireless access point, just set the wireless mode to “Access Point (WDS)”
The BT HH5a has two radios, so I set them both. This puts the option wds '1' in the /etc/config/wireless file.
So far - so good. On we go...
On the LAN Interface, change the default IP to a different one within the target subnet and disable the DHCP server.
Again, this seemed straight forward (apart from the darn thing rolling back before I could make a connection!). My Base AP is 192.168.0.1 and my new WDS AP to 192.168.0.2.
For a wireless interface (working on the same frequency band as the Access Point), click Scan, join the previously created wireless network and when asked, set the firewall zone to lan. The wireless mode should be Client (WDS) and the Network in Interface Configuration has to be changed from wwan to lan.
My understanding (and probably wrong!), is that the new WDS AP will have one radio "looking" back for communication to/from the Base AP and the other will be the access point for the additional WDS Clients I am hoping to service. Thus, as directed, I created the Client (WDS) using the 5GHz radio. Saving the 2.4GHz radio for later (Final step in wiki)
The next three steeps: setting the DNS Forwarding, IP4 Gateway & STP in the LAN interface are again apparently quite simple steps.
At this point, I figure that I could try testing. So ...
