Some of you may have good experiences with them but i certainly have not. basically the line has always dropped, after a lot of cs phonecalls it got sorted. Now recently, past 1-2 weeks the internet stops working (everyone is still connected to the wireless, jus the internet goes). We pay for 8mb and i dont think i've ever got above 2mb when i've done a speed test, i'll do one now and sod's law it'll be above 2mb lol. Here's the stats that may help:

Bandwidth (Up/Down) [kbps/kbps]: 1,278 / 5,887

Data Transferred (Sent/Received) [kB/kB]: 0.00 / 0.00

Output Power (Up/Down) [dBm]: 12.0 / 19.0

Line Attenuation (Up/Down) [dB]: 23.5 / 39.0

SN Margin (Up/Down) [dB]: 6.0 / 5.5

Vendor ID (Local/Remote): TMMB / BDCM

Loss of Framing (Local/Remote): 0 / 0

Loss of Signal (Local/Remote): 0 / 0

Loss of Power (Local/Remote): 0 / 0

Loss of Link (Remote): 0

Error Seconds (Local/Remote): 40 / 0

FEC Errors (Up/Down): 2,166 / 1,452,918

CRC Errors (Up/Down): 2,166 / 2,479

HEC Errors (Up/Down): 60,250 / 1,759



No idea what most of that means but you guys might. Any changes i should request with O2? and what about that fastpath thing, should i request that? Thanks!

edit: Does the following mean i get 5887 download? cause i've never achieved that, could it be that the router is rubbish or that im too far away?

Bandwidth (Up/Down) [kbps/kbps]: 1,278 / 5,887

done a speed test and got 5mb download which i never get, sods law. Ping was 48ms upload 1mb

Ok tomorrow i will do a test with it plugged into the master socket. May also remove ringwires, but is it sensible to ring them up and ask them to increase the snr to 9db?

Thanks
 
Yes you can, but you will sync at a lower speed.

SN Margin of 6dB, from what I know is the default profile.
 
hmm, i guess i'd rather sacrifice some speed for it to stop dropping out all the time, it makes online gaming impossible, and thats a big issue for me.

So what should i do, try all the options and see which works best? and whats this about fastpath, will that help speed at all?
 
Ignore the number of FEC errors. The router misreports them, and without either a time connected or the number of frames transferred there's no way to know how significant the rest of the error counts are are.
That said, there's no loss of {framing, signal, power, link} there. Are you sure you're still connected over wireless when it breaks, because it looks like the router's been restarted.

Indeed.
When it's dropping, it probably goes below that though. Asking O2 to increase the target SNR margin might get you more stability at the expense of speed, but it might not.

Disabling interleaving would make your connection worse. As suggested already, try your modem at the master socket with no extensions before doing anything else.
 
Here is mine in Southampton Using Thompson 780WL Downloading using Flashget at 7000+. You should do much better - get to the Master socket

The wireless shows up as connected and 4/5 bars which is the usual. It's so annoying cus like in gaming, i use ventrilo to chat and i always end up getting vital messages late so our team loses.

Router is connected to the master socket, i'll try putting it into the test socket.
 
Just plugged it into the master socket and its given me this:

Does that show anything?
 
posting another jus cause i guess it might be more stable after 20mins?

ok i pinged the default gateway, i got packets sent = 4, received 3, lost 1 and before it lost 3 and received one.

it also disconnected me from the router?

edit:
i also did a speed test which dropped to 3.2mb from 5mb last night?

it actually reset the router
 
What disconnected you from the router? Pinging it won't do that.
I was actually suggesting you ping the router when the "internet stops working", to be sure that it's not the router crapping out (which would hardly be a surprise).

If all your speed tests are from speedtest.net, you've been wasting your time. It's an awful site, and the results it gives are about as reliable as a chocolate teapot.
 
can you recommend a good test site?

well judging by the refreshed connection time i think the router reset, i dont know why but it happened when i pinged

uptime reset and the SN margin changed on the up by 0.5?

edit: i pinged again and all were successful and it didnt disconnect me
