Billion 7800N -early thoughts

InQ said:
I found that my downstream line attenuation was 42dB on G.DMT on the 1.06 range of firmwares (currently using 1.06e) but on the 1.05 it was 34dB. This lower value ties in with a Netgear DG834GT and a 3COM i have which also show either 33dB or 34dB. I think its just miscalcing the attenuation and it doesnt affect your sync.
As of today i am now on TalkTalk LLU with XILO (reseller) and my downstream attenuation is showing as 37dB so has dropped 5dB from the G.DMT value! On ADSL2+ it supposed to go up 3-4dB which infact it does compared to the Netgear and 3COM stats.
So to summarise i think the G.DMT downstream line attenuation in the latest firmwares is borked for some of us at least!

I am using Routerstats Lite to plot my noise margin over time, well worth a look and might help if you have noise issues.

I am also using Telnet to pull up more detailed router stats and its within that you can find out your interleaving depth or if you are on fastpath.
On Windows 7 you might have to enable/install Telnet, see here:- http://technet.microsoft.com/en-us/library/cc771275(WS.10).aspx#bkmk_installVista

Create a shortcut with the target telnet://192.168.1.254/

And once logged in to the router (your normal login and password for it) type or paste in adsl info --stats to bring up the router stats.

The "D" line nearish to the top will tell you your Interleaving depth, if its 1 then Interleaving is off and you are using Fastpath.

Thanks for info but my line attenuation has been same on both firmware.

It says D:16 on mine any ideas what this means?
 
I was using the Billion 7800 (not N), with a Sky LLU package and it always gave me great sync speeds.

Unfortunately, I am in an area that suffers from REIN which knocks the service out at various times of the day, so I went and got a wireless service fitted. No Virgin in my area, so it was the only other option.

When the guys came they fitted some POS T-Link box, so I copied the IP/DNS settings and hooked the incoming WAN aerial to the EWAN port on the rear of the 7800. The bonus was, I briefly had a dual WAN setup until Sky cut me off :p

My service (need a longer pole for the aerial, so it should be quicker)

Realyl happy I got to keep the Billion, the features it offers are 1000x that of the router they supplied. Plus the ping is much lower :)

Interleaving is on with a depth of 16. See here - http://www.kitz.co.uk/adsl/interleaving.htm

Do a pingtest to the BBC.co.uk ie in a DOS box type ping -n 10 www.bbc.co.uk and paste your results here. I see 33ms which is pretty good with interleaving enabled.

26ms not sure if im pushing boundarys of my connection with setting SNR to about 6.1 to 6.3 it jumps between numbers a lot according to routerstats.
 
Looks ok to be fair to me.
FEC's are high but not sure if that means much....
If you increase the noise margin it will lower your sync speed, thats how it works.

What are you wanting to do? :confused:
 
Just turned phyre on with mine and have seen my speed jump from 3150K up to 3855K, which is nice. Am about 6km away form the exchange, so think I have just about maxed out what i can get.

Did the ping test to the BBC that was mentioned a few posts back and get min=27ms, max=28ms average=27ms with zero losses.

Rest of the figures wise have SNR of 9.4 and 3.6 upstream and downstream respectively as have set the SNR tweak to 1. When i first altered it, it jumped to over 4000K on the connection, but settled down to the 3150K. Will keep an eye on the up time to
 
Hi,

I have one of these Billion 7800n routers, and was wondering, if anyone knows how I can change the MTU setting? I am on O2 LLU broadband and have been informed by them that it should be set to 1500. The firmware I have at current on the router is 1.06e

Thanks

Yes, click advanced, then Configuration, then WAN Profile and its there on the right.
 
Wizkid,

You can always run through the Quickstart option that's on there. That's where I changed my MTU setting. It is covered in the quickstart hard copy guide that comes with the router. You can get a copy from here
 
I bet the MTU is set to 1500. Every router I've used has 1500 as the default MTU value. A lot of them have MTU value of 0 which means it defaults to 1500. I'd still follow the advice above to make sure anyway.

Hi

Thanks for your response, I have done the quick start up and its not listed there either. I have just selected another option under Protocol under WLAN Profile and the MTU option is listed, but its not listed with the Protocol that O2 require the router to use. So I assume that there is no way that this can be changed?
 
Sorry for my distracting answer earlier.

I DID NOT have to change my MTU to get my 7800N working with O2 LLU. I just ran through all the steps in the quick start guide and was up and running after the router re-booted itself. Then tweaked the SNR and turned on Phyre to get the most out of my line.
 
I'm tempted by one of these routers. I'm currently using a Netgear 834g v2 on an ADSL max interleaved line at 8064 sync. 21cn ADSL2+ is available. I tried it and it worked fine until I turned my plasma tv on. When I turned it didn't lose sync but there was zero throughput. As I didn't have the time to investigate the house internal wiring at the time I just reverted back to ADSL1 and it's been solid since. I'm currently im the process of checking through the entire house internal wiring including disconnecting the ring wire.

Our local council has recently been awarded a grant to cover the country with high speed broadband.

Although it's still in the early stages my current router is only good for ADSL and ADSL2 so wouldn't be of any use for any future fibre services whereas the Billion I understand can be used as a separate switch.

Also my Netgear wifi speeds are pretty poor (maximum 1 megabyte per second). For web browsing it isn't a problem but for streaming HD video to my Xbox or transferring files over the network it's pretty pants.
 
back again guys i did ask in august but no one said much :P

anyways my current stats on the ole home hub 2 are.


Downstream
3,392 Kbps

Upstream
448 Kbps

Noise margin (Down/Up)
9.3 dB / 17.0 dB

Line attenuation (Down/Up)
49.0 dB / 26.0 dB

Output power (Down/Up)
18.8 dBm / 12.3 dBm


yeah not great numbers, im on a market 1 exchange so no llu or even 21cn here. im removed the ring wire so now im stuck with looking at a better router. so would the 7800N be much of a step up or would i be better off setting up string and tincans :(
 
Well, I have just joined the club and ordered a Billion 7800N.

My old router has been playing up the last few weeks. Seems this router is still the best choice at the moment after doing a lot of reading on these forums!

Heres hoping its easy to set up and transparent in terms of network users / settings etc. :)
