Billion 7700N vs 7800N

Just wanted to know before I make a purchase, is the 7700N got the same chipset as the 7800N which I hear so many fabulous things about.

Kind Regards
Edd

I was under the impression that the 7700N also used the Broadcom 6358 chipset (used in 7800N) however this isn't true. The 7700N uses Broadcom 6328 which might not be as good as the 6358 but i don't think it will be poor as generally speaking most Broadcom chipset based routers perform very well.

In a nutshell, the 7700N is a good entry level router for a simple home setup but if you want something more powerful (more RAM) with more features, then the 7800N is the one to go for.

The 7700N is completely different to the 7800N. For the testing I have done so far, both hold a line set to 1db very well.

I left the 7700N connected on Friday and it has not dropped as yet, but the 7800N could manage weeks without a drop, so it'll take a while for me to really say how good the cheaper 7700N is.

Hi Uno, what I wanna know is what is the difference in sync speed? Is there a major noticable difference? Because at the moment on a 68dB line we sync at 2692kbps with an SNR of 6 on a BT Business Hub (faulty).

I think that's a bit dependent on the line, different routers will cope with different line conditions in different ways, but, FWIW, my 7700N syncs at a slightly lower speed than my 2700HGV used to. Still very acceptable though, and seemingly quite stable.

Currently 44.5 attenuation, SNR of 0.9 and a sync of 7681 (ADSL2+)

EDIT. Ooops, just noticed you are talking about 7800 v 7700. Ignore me please :=)

It's probably worth pointing out that setting a 1db Target SNR margin will only be ok for those on nice stable/quiet/short lines!

Unless there's some magic in play here

Well don't know about only short, depends on what you mean by short really, my line isn't short in my opinion,nor do i consider it to be long, ( att of 29db ADSL2 +) My ds margin is set to 1db Isp is be* Fast path using a DG834 Dgteam fw, all is stable with a 2MB/S throughput until a local business starts up, not my line at fault ,but some one else's line or what they have connected to it

Put in an order for it today, is there anyway of getting the SNR tweaked without telnetting it? I saw something that said you can tweak it from the firmware like on the 7800N... Can anyone shed any light?

No, you can't tweak the SNR from the firmware. However you can use the DMT tool v8.07 tool to adjust SNR in Windows:

(make sure Telnet is enabled for DMT tool to work)

The 7800N has:

Gigabit LAN ports
EWAN port
IPv6 Support
Better firmware
Better QoS
Detachable antennas
Third antenna
Different Wireless Chipset
7800N has Ralink wireless, whereas the 7700N has Broadcom.
Bigger NAT table
VPN & other features

and a tweaked SNR will survive a reboot
