Will the Broadband stop working ?

A company i know have just ordered an upgrade on their Broadband fron an upto 8Mb package to an upto 24Mb package. The problem is i think the router they have is only ADSL compatable a fairly old Belkin.

Therefore my question is what will happen when the upgrade takes place
1) Stop altogether
2) Negotiate back down to ADSL
3) Other.

and if it stops altogether or becomes unstable what can be done. Will a firmware upgrade work or will they definitely need a new router. If so which one.

Bearing in mind they have 6 PC's, 2 printers and at least 1 Laptop connecting to the Network either wired or wireless. The two printers even though on DHCP are set to receive same IP address every time.

At least two are wireless N devices, but working fine on the wirless G Network.

What model of Belkin? You should be alright if they're using new N technology. It is possible however that the DSLAM won't like the router, but that all depends on what they put in at the exchange and the router your using.

It should negotiate back down to ADSL.

But bear in mind that a 20 Magpackage may not make any difference if they are too far from exchange, say over 3 km line length.

What speed are they currently getting? What are their router stats?

Exchange is about half a mile or slightly less.
Can't remember what attenuation is but downstream synch is 7616 and upstram is 448 at the moment.

Haven't got Model number in front of me.
But looking at Belkinn site looks like the F5D7231-4 router.

Should be able to get ADSL2+ on that model

In reply to a post by TTEnt:

Good! They are getting max. from ADSL, so switch to ADSL2+ would benefit.

It should work, but did see a DG834PN refuse to work on an ADSL2+ Annex M line from Tiscali/TalkTalk

Firmware upgrade and viola it was working.
