Thanks for the replies folks; Andrew, I didn't really mean rugged in mechanical terms LOL; thought it may have been designed a bit better electronically for 24-7 business use; perhaps the Home hub3 and Business Hub3 are the same animal.

MHC; perhaps the old 3Com router was poorly designed to handle the ADSL2+ which working at higher frequencies could conceivably be more prone to noise.

Anyway, I'm more than happy with the improvement with the BT hub and with the 'possibility' of FTTC in the coming year should see an even better improvement when it happens; maybe 18Mb! My 8Mb speed coupled with the low contention rate on Business broadband does everything I need at present.

Thanks,

Mike.

Looks like the 3Com stats might be plain ADSL, as the sync speeds are divisible by 32.

Looks like you might be right.
That would also explain the difference in reported attenuation.

No it doesn't, the attenuation has gone down not up.

Good spot!

Just a small question about BT Business Broadband.

I use the speed test on this site which I find excellent.

Can anyone tell me why my IP address changes every day or two; I don't have any disconnections my end; the Hub3 is on all the time and not in saver mode.

Twice this week, Friday and this morning I noticed a drop in speed from my normal 7.5Mb-8Mb to around 1.5Mb and a change of IP address.

A restart of the Hub3 and a reboot of the computer brought a different IP address and the 7.5Mb speed back but was wondering why they would keep changing IP addresses throughout the week if I didn't disconnect my end.

I know I haven't got a static IP address but just wondered why this happens?

Mike.

Maybe the line drops at a time you don't notice.
Or another is that BT drop the sessions occasionally, without making the broadband drop out.

When the speeds are slow next time, check what speed the modem is connecting at.

Thanks for your reply Andrew; I'll check the stats next time.

Perhaps it's just one of those things BT does, as you say.

On all the IP addresses I usually get around 7.5Mb+; I couldn't understand why it would suddenly drop like a stone on odd occasions. Guess it's just life.

Mike.

It will drop because if there is a noise burst - e.g. lightning the modem drops and maybe reconnects while the noise is still bad, but will now stay at the low speed until you come along and give it a kick.

Standard DSL behaviour all over the world

I've installed a number of these Business hubs for friends, a few on long lines. Used various models and firmwares myself for years until I bought a Billion router. Very durable, stable, good on long and noisy lines and they are daft cheap on fleabay. After the usual cabling issues have been fixed I found one of these would often improve dodgy connections for little money.

Still have several in the cupboard as spares.
