Hi guys, I was just wondering if anyone could tell me whether I'm reading these values right or not:

NETGEAR%20Router%20Statistics_1231802238428.png


I assumed having poor wiring was the reason for a slow speed, as it seems my house's wiring isn't great, but I saw this speed calculator which seems to indicate I should have a higher or lower speed.


If I'm reading it right then I should have a pretty good sync speed, the previous calculator suggests 24meg, unless I read the numbers wrong and I should be entering 56dB in which case it should be about 3.7meg which is closer to what I get in reality.

I know it's only an estimate anyway though. I figured that line attenuation was low which is good as it means less degradation of the signal, and the SNR wants to be as high as possible as that means there's less interference from noise. If this was the case though I'd expect much higher speeds, so if anyone could point out where I'm going wrong I'd appreciate it.

I'm with BeThere so it should be able to go up to 24meg max, so it shouldn't be limited by my isp.

Thanks :)
 
The line attenuation indicates how far you are from the exchange in terms of line/copper length. Now having a downstream of 2.6db indicates you must live either in the exchnage or right next door to it if it is reporting correctly. Your SNR is really high though and should only be at 6db.

This means it could be an internal wiring issue as you should be hitting 24Mb easy. S as suggested plug your router into the master socket directly and see what you get as that will cut out all the internal wiring you may have.
 
Thanks for the replies guys, I posted this on the bethere forum aswell and they suggested using the official bebox to get some line stats (I stopped using it as it developed an intermittent fault and would drop the line very few hours)

I think tolien is right. It looks to me like the modems are disagreeing on which stat goes where but the stats from the bebox would explain the slow line speed.

The wiring in my house is maybe 25 or 30 years old so there isn't a test socket I can plug into, there's just 2 wires behind the faceplate that go off to another socket, which is where I had it plugged in. Looking at these stats though I don't think I can really expect a much faster connection than what I currently have :(
 
There are just two wires in both sockets right?

If so, then there's probably not much you can do.

You can check your maximum MTU although the results will probably be negligible. See here for instructions.

Yeah I had a quick look yesterday, I think that's all there is. Do you know if there would be any benefit from fitting a faceplate with a built in filter? I'm sure I've read that it's better than a standard filter as it's closest to the point where the signal enters the house, but given that it's pretty poor as it is I'm thinking it's probabaly of limited use.

Thanks for the help :)
 
I got an extra 500 kbps by fitting an XTE-2005 faceplate and using a Pro RJ11 cable.

What configuration are you on with Be? Log in on the homepage and see if you are on optimised or standard (bottom right of the page).

If you are on standard, try changing and then see if your line is stable (it may retrain over a couple of days). If that is stable then you can try turning gaming mode on (interleaving). This won't necessarily increase speed but may reduce pings.
