You sure? That looks like a pretty good normal ADSL Max line to me.
Man of Honour
I know but if Taken's exchange or connection hasn't been upgraded to ADSL2+ it's irrelevant.

Still trying to figure out how to get these error stats, back home now for lunch so shall have another try!
rpstewart is correct in that we have no ADSL2+ enabled in our exhange unfortunately!! See Here > http://www.samknows.com/broadband/exchange/WNWXL

Just plugged it in, first sync is 200kbps faster downstream than I usually get - SNR seems to be a bit less jumpy too. Got to find out how to get RouterStats to work with it now!

Does anyone else have issues with reconnecting to the internet after the 7800N has been idle for a short period of time? I've got my connection set to always on but whenever I connect with my laptop, phone or desktop it takes ~40secs for the 7800N to respond, in the meantime everything just times out. I can ping the router just fine during this period though.
No, what firmware are you running ?

1.06d.
I've narrowed it down a bit. It seems to happen on every new browser session, I simply get "Resolving proxy..." in Chrome which can be fixed by forcing it to not auto discover a proxy, however I can't find an option on my iPhone for this so it takes forever to load every page while it tries to find a proxy server. This has only started happening with the Billion, for some reason it's making my PC's think it's got a proxy server on board!
OK I love this router, taken me from a patchy 2200kbps line to a stable 3100kbps line so sweet.
Question though, I set my snr to 75 to bring my snr down to just under 6db. The line trained to 3500kbps but has ended back down over a few days, while the snr has climbed to 9.6db. Is this the Telecom dslam trying to compensate?
Does it mean I can tweak the snr even more aggressively?
..and thanks to dmsims for the review and the thread, helped a bucket load!

*make sure you know your username & password for ADSL account, and the default admin/password for the router
Do a full factory reset on the router, it may flush out any ghost settings. Then configure it again, worth a shot

Thanks bledd. That is exactly what Billion suggested I do too
I've found out what is/was causing it, although I (nor Billion) have any idea why it would cause this to happen: setting the wireless channel width to 20/40MHz. This causes wireless AND wired clients to have the same problem, I could understand just wireless clients and not wired, it's a very strange problem. Apparently Billion are looking into it

Sorted this yet Kona?

Does the Billion 7800 have holes/grooves for mounting on a wall?
also, how do you tweak the SNR on it? Is it via 3rd party app/firmware? How easy is it to do compared to the Netgear DG834GT?

Yes
Just a URL to the router
http://192.168.2.1/snr.cgi
You can't tweak the SNR on DG834GT (with std firmware)
Soldato
Cool. Which way up does it go? Network ports down would be easiest, but not a deal-breaker.
You can via the command line/telnet. Unless I don't have standard firmware (was bought second had but appears to be V1.03.22.
Don
Yep, you have a noisy line, it isn't stable at 6db so the DSLAM raises it to a stable value, which appears to be around 10dB. Lowering the SNR is pretty pointless unless you have a genuinely noise free line that can operate stably at under 6db, otherwise after a few line drops the DSLAM line stability algorithms will raise the pre-modified value and counteract your adjustments.
