Line Attenuation/Noise Margin

[Pooky]

I have a Mega105WR router, I'm not sure if these are the correct stats for Line Attenuation and Noise Margin:



What's the difference between US and DS?

What's the difference between US and DS?

US = Upload Speed
DS = Download speed

 

[Pooky]

US = Upload Speed
DS = Download speed

Oh /facepalm thanks.

 

[Lycanthrope]

US = Upload Speed
DS = Download speed

US = Upstream
DS = Downstream

The DS margin is VERY low, check your line for sources of noise

I wouldn't have the first idea how to do that, can you explain?

 

[Gadget Man]

Have you been upgraded?

 

[Pooky]

Have you been upgraded?

Yes, I'm syncing at 4mb

Are you having issues or am I missing the point here?

No issues I don't think, just Segg said I should check my line.

9 is still in the acceptable range, if you used a better modem it could increase it but why bother if your Internet is fine. Since your modem doesn't show anything after 9 it could even be closer to 10 than 9.

It went up to 11 when I checked just now.

6dB or below is very bad and will experience no sync or intermittent sync problems
7dB-10dB is fair but does not leave much room for variances in conditions
11dB-20dB is good with little or no sync problems
20dB-28dB is excellent
29dB or above is outstanding

Also your attenuation is great, easily enough for 20Mbps.

Cool thanks for your help. The Telkom guy I spoke to this afternoon said my router could never handle 4mb because the new routers have some filters built in...

He also said they were going to upgrade my exchange to 40 mb which is cool I guess even though I won't use it

 

[Soul Assassin]

Those aren't the best routers in the world but it's still rated for a theoretical sync of 24Mbps. The nice thing about having your line sync faster than your account is it eliminates all overhead, for example if your line syncs at 4096kbps with a 4096kbps account you should see speeds of around 420kBps but without the overhead you would get 512kBps.

26 DB down isn't bad at all mine is 28 and can get 20 meg+ attainable.

Your Upstream at 15 db seems way low for your stats should be close to 30 db or more, but you should get 1 meg upstream when they upgrade again anyway.

His upstream is 20, way more than you need for 1024kbps.

Nee thats not right...your router can do 4 / 10.

He probably meant 40...for that you need a different router. Not sure what he meant w/ filters though...

 

[Soul Assassin]

Just realised that now, he probably only meant if you're upgraded to 40Mb you would need a VDSL modem, the filters thing is either he doesn't actually know how it works or didn't want to make things complicated.

Lol read them wrong way

His downstream is very low at 15 db SNR or 9 Margin so its either the router or the line has a fault.
