Looking for a new router - Page 7

Fridges, central heating and so on can cause interference.

The atm stats look okish, your downstream SNR isn't especially healthy and knowing that as sync rate increases, SNR decreases (hence SNR targets and so on), what SNR do you get when it syncs at 7Mbit or whatever it was?

There is nothing in this house that comes on at the times when the connection gets flakey. 17:30 on Mon, 18:30 Yesterday and 16:20 Today. It's pretty much unusable for the rest of the evening until i turn it back on in the morning. My Zyxel has been synced for over 10 mins now but if i switch the cable over to the Cisco it just won't connect. Stats on the Zyxel:

noise margin upstream: 9 db
output power downstream: 19 db
attenuation upstream: 19 db

noise margin downstream: 10 db
output power upstream: 12 db
attenuation downstream: 36 db

The noise margins always used to be bwteen 15 and 20 from what i remember (with previous isp though). I can't believe the Zyxel is so much more robust that it isn't effected by whatever the problem is supposed to be.

What Sync speed is the Zyxel reporting?

What microfilters are you using?

CliffyG · 22-11-2006, 21:30

WAN Port Statistics:
Link Status: Up
Upstream Speed: 832 kbps
Downstream Speed: 5408 kbps
Node-Link Status TxPkts RxPkts Errors Tx B/s Rx B/s Up Time
1-PPPoA Up 16017 15076 0 0 0 0:33:05

The router plugs directly into the main incoming wall socket which is in the study. I only have 1 splitter in the house and that's where the phone is in the living room.

Mark · 22-11-2006, 22:08

So does that mean you have a faceplace with a built-in filter?

The sync speed the Zyxel is reporting and the speeds you reported the Cisco trying to sync at suggests the Cisco is trying to negotiate a faster speed than the line can handle. Back to my previous suggestion (going to need a DSL command-line expert for that).

CliffyG · 22-11-2006, 22:31

Nope, you dont need a filter unless you have a phone plugged into the socket.

I think it's dropped like that due to all the swapping i've been doing. Will leave it on for a while and see how it syncs next time, i think it will be higher.

I'd fit one anyway tbh dude. I know what you're saying, but I know guys in the same position as you who've had all their problems vanish with a filter. Not least because anything incoming will upset the connection, phone on the end or not.

CliffyG · 22-11-2006, 22:57

I did try one in but it hasn't made any difference to my problem. I've had adsl since it first came out and I've never used a filter before, never had any problems.

Mark · 22-11-2006, 23:27

I got myself an NTE5 (faceplate filter) from day one. Not regretted that one bit. However, at least in that case the ADSL side does nothing (I've run a phone on the ADSL side without a problem).

Newer filters like the XTE-2005 may well be different.

Been stable for over 2 hours on the Zyxel now.
