Long line and lots of noise advice on router required.

g7pkf · Jun 09, 2013, 11:26:11

I have a very long line (attenuation 50dB) and the lines run over a main line railway so lots of interference.

can someone advise a sutible router that is in production? my trusty old 2wire is on it's last legs and i want to look at alternatives, as not only do i need a new router so do a few of my neighbors as they have the same problem.

Maybe worth seeing if you can pick up a Billion 7800N, there's often a few on eBay however some seem to attract too much money imo.

I've been using one of those recently, and everything seems fine with it.

I'm another fan of it, although only used it on ADSL2+ for a couple of days before moving over to FTTC.

The best modem would be a usb one with a sim card in it...

/no help

But other than that, I wish the best for you, sounds a difficult line!

Well it wouldn't for my parents. They only have a 2G signal.

Long line at 50dB? I'll raise you their 58dB. If it weren't for the line noise they'd get a consistent 4Mbps connection (with about 6.5dB SNR margin).

Dean's biggest problems stem from the railway line he mentions.

Of course. An electrified line is a good source of impulse noise.

Has anyone got one of these to work with a mail server on the inside? pretty sure i got all the setup correct but it just is not allowing email in

i can send fine?

anyone?

Lance is your best bet, he runs his own mail server and from this thread a 7800N. Are you using NAT or a pool of WAN IP address? I think it struggles to do both together although from the link you could have a second router providing NAT to the other local devices.

I've enabled ports in two different places, but I think only the port mapping side is actually required. See attached

Steve · Jun 12, 2013, 13:21:54

So that's the single WAN IP address solution.

Thanks got that working fine now.

Excellent
