Post your FTTC line stats & unlocking info

[ChrisD.]

I use my own router.

How will I know when I'm on a good one? My ping plot with thinkbroadband went mental when I used Usenet.

You need to cap download speed if you don't want jitter. Line saturation always causes it.

Here's an example:



Torrents seeding 24/7 (upstream QoS enabled). The download kicked off at 4PM caused the latency to rise. Power cut experienced shortly after 4PM, latency returns to a very low figure and packet loss disappears.

Just seen this comment. I will limit the download speed to a few 100 kbps below the max speed. I don't download often, so it won't really affect me that much.

OK - so ive flashed it and all seemed ok, I can log into the web interface, but i get like 10 seconds and then the connection seems to drop :S

Any suggestions ?

Cheers

Have you tried Telnet into the modem, is the default IP of the router same as the modem?

 

[{SAS}TB]

Hi - no I havent tried Telnet and not sure anout the IP - Ill check both when I get home from work tonight.

I can access the router menu, it's just for #10 seconds and then the connection drops :S

 

[Locky]

If your modem and router are both on 192.168.1.1 then it might cause a conflict.

Hi guys, just looking for some assistance here could you take a look at my stats below please? I'm 500m from the cab and was estimated 35 meg, something doesn't look right to me. Thanks!

500m of copper?

 

[Balb0wa]

500m of copper?

Must be Aluminium , cant see BT doing anything as its over 15mb

 

[JoshShep]

It must be Aluminium, what speeds would I be getting if it was Copper? My connection is also very unstable and I'm experiencing pings of about 40ms, being a gamer I find this very frustrating, my connection was more stable on TT LLU, because DLM didn't take part!

 

[Locky]

Looking at the attenuation, it's much much more than 500 meters, closer to 1k, or as above a poor alu line.

but hey, 33mb is better than what you used to get right?

Hes getting 26mb though, i have 1060 metres of alli, i get 14mb

 

[JoshShep]

Just done a modem re sync, these are the results I'm getting now, I've calculated the route via Google Maps and I'm 550m from the cabinet, the drop wire goes to a telephone pole and underground to the cabinet, I believe most if not all the cabling is Aluminium. Here are the stats...

Should I ask my isp (TT) to higher my throughout put speed? It looks to me like they have capped it? I should be syncing around 35 meg from the looks of it.

Thanks for the help guys! This fourm is really helpful.

 

[ChrisD.]

Not on alu you won't.

 

[JoshShep]

I don't understand, My line is capable on 36 meg, I was estimated 35, I see people on here getting within 2 meg of the max speed capable, my path speed is 28, something must be wrong. if my max speed was 30 I would be happy.

 

[Balb0wa]

my line rate is between 19-21 , i get 14, id be happy to get 19

I've been running some graphing scripts for a the last fortnight.

Ok, but what was you estimated and how far are you away from the cabinet?

Thanks

Estimated 12, 1060m of wet string (Alli) , estimates are estimates, could be higher or lower
