 Weaver, now your broadband is a little better could you not compromise, and connect to the internet via modem/routers, not modems only. That way, you could connect wirelessly to the ethernet network without extra things attached to your modems. Total break between the modem/router and the rest of your network. I realise it would involve four WiFi channels, but the airwaves around where you live are hardly congested are they?  As I  mentioned before, my storm protection plans if implemented in time, use this method, with the rest of my network in a different room.................

Ronski - done. I have some expensive Belkin AV surge protectors for the mains but I have never had a surge/strike through the mains, it’s always the dsl which is vulnerable.

But some have surge protectors for the DSL.

Ronski - thanks for that

Benji09 I had thought of this using wireless as an air gap. Still considering it.

It turns out then that I was wrong. The problem with the VLAN MUX switch is not fixed at all. Was running with three modems in direct bypass over the weekend. Had a session with AA this afternoon but they cannot get the switch to work. Reinstalled the switch config and still no joy. Back to direct bypass mode, straight from FB2900 direct into three modems. AA totally flummoxed.

Anyone know anything about VLAN switches ? I could post up the switch config which is in ASCII.

Would you please post the make and model of that small switch (being used as a mux/demux device)?

[Weaver]

It’s a ZyXEL GS1900 switch.

It’s a ZyXEL GS1900 switch.

Thank you. b*cat now goes to download all the relevant documentation from the ZyXEL ftp server.

Any kitizens wanting to help us out would be very welcome because this is a bad situation, been struggling for ten days now and it appears that it’s just this stupid switch thing that is the problem. Have got rid of all the bad kit, all cables replaced systematically and things work when I bypass the  VLAN switch. I don’t think I can get the config out of the original switch because Janet said there were no lights on it, perhaps worth taking a second look.

I can post the switch config if that would help.

Just to confirm, it is an eight-port ZyXEL GS1900-8? 

[Weaver]

Correct. 8-port


What other stupid things might we have done, instead of AA? I asked Janet which ports she had plugged the various cables into and the MUX switch port 8 goes to the firebrick port 4; the firebrick’s VLAN config has combined FB` physical ports 2, 3 and 4 as one WAN port, and it doesn’t matter which of those she uses in the Firebrick, but FB port 1 has to go to the main LAN switch. On the GS1900, port 1 is modem 1, port 2 is modem 2 etc the Firebrick expects to see incoming MUXed traffic with modem 1 on VLAN 101, modem 2 on 102 etc

Hi

Is the switch powered on and live ie can you access the login screen and log into switch

It could be eco mode so lights off

If you cannot access the switch gui - it is likely dead - check power lead/supply

Many thanks

John

Hi John, I’ll ask Janet to take another look at the switch that she said was dead. I have been using the replacement new switch that AA sent at the end of last week. That was the unit we were using for today’s unsuccessful session. We haven’t spent much time on that original no-lights switch, just swapped it out. But it would be good to look at the config in it.

I seem to remember seeing a switch config on AA’s support.aa.net.uk website https://support.aa.net.uk/ZyXEL_GS1900-8 - I would have thought that there would just be a backed up standard config file saved so AA did not have to invent it every time, but perhaps I’m being very unfair, and I don’t really know what I’m talking about.

[Weaver]

I need to give AA some more time to think about the problem. I hope I’m not doing something really stupid and wasting a lot of everyone’s time, but I haven’t changed anything at my end, apart from replacing cables, after the lightning strike. I’ve emailed AA’s general manager to ask for some guidance. It’s all a bit worrisome and disappointing.
