I replaced my becoming-flakey Netgear with the current PlusNet default TG582n for my fibre b/b, and I'm generally pleased with it.
However, the Netgear had an isolated guest wifi option which I liked, so I tried to replicate this on the TG582n. This was done largely with something like (deduced from the ever-helpful telnet commands site often linked from here):
wireless mssid list
wireless mssid ifadd ssid=your-guest-ssid-name-here
wireless mssid ifconfig ssid_id=1 apisolation=enabled secmode=disable
wireless mssid ifattach ssid_id=1
eth bridge ifadd intf=wlan_1 dest=wl_ssid1_local0 logging=disabled
eth bridge ifconfig intf=wlan_1 logging=disabled
eth bridge ifattach intf=wlan_1 logging=disabled
Now, I thought this was working, but after a day or so it became apparent that it had made the normal wifi connection exceedingly flakey: our wireless devices were working briefly, then dropping out momentarily, before reconnecting and working again. As soon as I disabled the new guest I/F, it all became reliable again.
Can anyone explain why? Is it something to do with the following output?
=>:wireless mssid iflist
ssid 0/0 : [real] [up] Security: WPA-PSK
ssid 0/1 : [guest] [down] Security: None
I thought it suspicious that the IDs were 0/0 & 0/1 instead of maybe 0/0 & 1/0. Not that I know what they mean.

The second number is the SSID number, the main station is "0" any additional virtual stations are 1, 2 or 3.
The numbers are correct but the lack of security is worrying.
Have you seen this:

Or if you wish the guest wireless network to be isolated from the main network:

Does this also apply to the TG582n as identified in the OP? This page says "Multiple SSID's on a Thomson TG587n", it references this not being applicable to 585v7 but makes no claims for the 582n. If it is applicable, is that valid for all 582n? (W/wo USB interface).

I read a few of the pages, and used the multiple SSID page to achieve what I did (including the extra “bugfix” bridge setup which I found I needed). The DMZ config. is way OTT for my needs (although I suppose I've effectively got that with my internal Linux firewall configs anyway).
While a great resource, the main issue I have with that site is that it's more about recipes than documentation, so while there are a few comments it doesn't really explain in enough detail what's being achieved (& I like to think I know a bit about networking and firewalls).
So yes, that's what I did, it just made my connection really flakey. I may try it again with simple WEP on the guest connection (like @RPMozley, it's also to allow NDSs to connect while I keep WPA2 on the main connection), in case the wireless devices are being too eager to jump between available SSIDs and see the open guest as a good bet.

The 582n was not out when I wrote that web page. Thing's move on
I haven't tested multiple SSID on the tg582n, but the commands are supported so I see no reason for it to not work.
@ fnxweb,
I assume the NDS doesn't support wireless "n". Some old wireless g devices can cause problem with the routers wireless, try disabling wireless n in the router. You'll find the command in the telnet page of that site.

Heh, I haven't even tried the NDSs yet; the connection problems were with a number of (n-capable) Android devices, and also possibly a couple of standalone wireless security cameras (which were playing up and now aren't, the subject of a future post).

I removed it again and all was fixed. Guess I'm just out of luck 😞

I've followed this guide for my 582n, and it's worked great. My only problem is that the guest wifi network can still see files on my shared WD Live drive.
I used
apisolation = enabled
but that doesn't seem to have done the trick. Am I missing something?

Alternatively you should be able to block access to the shared drive using the routers firewall.
Try a firewall rule allowing access to the share from whichever IP addresses you wish to allow.
Followed by a rule blocking access to the share from LAN.
You may need to experiment a bit but something along those lines should work.

Thanks for the reply and your excellent guide.
Just so I understand what I'm doing - the DMZ should sit separate from everything else in terms of access, so if my existing Wifi is 'SSID1', and my guest wifi is 'GuestWifi', then when I run 'eth bridge vlan iflist' I should see the ethport with my WD Live NAS in default, and the 'GuestWifi' in the DMZ?

If you just chose the wifi option (d) then nothing connected to a ethernet port or on the original wireless ssid can be accessed from the new (dmz) wifi.
ie "eth bridge vlan iflist" will then only show:-
2 dmz OBC, Wdmz*
Good luck, please let us know how you get on.

Still a bit stuck I'm afraid. I can't figure out how to link what I see in the list with
eth bridge vlan iflist
and my actual SSIDs
when I type 'eth bridge vlan iflist'
I see
Vid Name Bridge interfaces (* = untagged)
--- ---- --------------------------------
1 default OBC*, ethport1*, ethport2*, ethport3*, ethport4*, WLAN*
, wlan_1*
2 dmz virt*
I temporarily put wlan_1 into the DMZ but I'm pretty sure that was wrong so I put it back! Then I put 'virt' there, but my virtual SSID can still see my NAS.
Any tips, please?

No, virt is the usb content sharing.
you need:
Vid Name Bridge interfaces (* = untagged)
--- ---- --------------------------------
1 default OBC*, ethport1*, ethport2*, ethport3*, ethport4*, WLAN*
2 dmz OBC, Wdmz*
Note:
Wdmz was the eth interface name first used in the instructions to create the dnz ssid. You can use a different name but it need to be consistent through out.
You may be best doing a factory reset and starting again.

One thing that's gone wrong now is that I can only get 'Limited access' on my virtual SSID - nearly there!
