-My bad, i think i asked way more than two questions 

[kitz]

You can access the router using the IP address 192.168.0.1 to perform the actual firmware upgrade without having to have an internet connection.

However - you will need to download the firmware which does obviously need an internet connection, so make sure you download the updated firmware to your PC.  Then when you start the firmware upgrade point it to where you have stored the upgrade file on the PC.

[broadstairs]

Just to add that you should always do any firmware upgrade via a wired connection if you have one....

[Rahat]

Thanks for the tips/help. I'll let you know when i get the router and what it syncs at.

[jid]

Just to correct, the IP Address of the router is 192.168.1.1

(sorry to be fussy Kitz )

I would go ahead with downloading 2.61 as it has the exact same setup properties as shown in that setup guide.

Also make sure you use Internet Explorer for the upgrade as it won't work with Firefox...

Also you got a good price for the router there too! 

Keep us updated on how it goes:D

[Rahat]

Will do mate!

Hi everyone, i finally have the 2740b. I just setted it all up but im finding th statistics quite difficult as it's way more complex than then o2 router. Oh yeah, and i've updated the firmware to 2.61.

Well, here it is lol. I got the dmt tool to work and just lowered the noise margin to 2.9 but when its about 12PM or so i'll up the noise margin and see whether or not i can keep the full 8188 sync.

[jid]

Ok.

• Super Frames Errors are CRC
• RS Corrected are FEC Errors i.e they don't affect throughput

Like I have posted in the past, Adjusting the SNR Target in the morning would be best as it would give you a faster speed, however this might effect the connection later in the evening.

What did you move the slider to in DMT, out of curiosity?

From your stats you posted in October the Sync speed looks improved, what sync were you experiencing on the old O2 router? Was it about the same or higher?

[Rahat]

Pretty much the same to be honest. I've been getting the full 8188 with a 3db noise margin with the o2 router. However, i used to have wierd upstream snr fluctuations whenever the phone was picked up but it looks to have steadied with the new router.

By the way, what does RCO mean on dmt? Under my sync for up and down it says RCO and shows me another sync speed.

I havn't tweaked it yet, still on 100%

[jid]

I would try tweaking it, see what you get

As for RCO, it basically is what your line could handle with the current conditions, or something along the lines of that. (if Kitz of one of the other gurus could clarify)

As for the % next to it, when I sync at 8128 it shows 100% so I imagine it is something to do with your sync speed relating to quality...

[Rahat]

Ok then, the RCO had 10626kbps for downstream so if i upgraded to 16meg package would i have synced at that speed?

[Rahat]

I doubt it because if i sync in the afternoon i barely get 8meg.

[Rahat]

So can anyone clarify what the RCO sync and percentage is? Thanks

[kitz]

From the DMT pages @
http://www.kitz.co.uk/routers/DMTv8.htm
it tells you what the figures mean

RCO - Routers estimation of maximum achievable sync speed on adsl.

the percentage figure  is simply that - actual sync as a % of the RCO.

[Rahat]

So you're saying i may sync near 10meg (estimation says so)? I doubt it because i can barely sync at the full 8meg unless i do it during peak time.
