Weird DGN2000 problem

Hi All, i've recently connected my DGN2000, to my O2 connection and have noticed that the WAN dosent seem to manage to stay connected for my than around 4 hours at a time, it dosen't lose Sync btw !! i've tried changing DNS servers, and MTU e.t.c, the actual O2 Box seems to work fine so it isnt a connection fault.

Here are stats >

Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time
WAN DHCP Client 254221 322046 0 13521 35978 02:45:18
LAN 10M/100M 434057 310910 0 2906 915 42:16:22
WLAN 11M/54M 52239 26519 0 127 208 42:15:56

Any ideas would be appreciated.

hi
can you post your full stats .
this link might help
Regards Jeff

Sorry forgot those, here you go >

ADSL Link Downstream Upstream
Connection Speed 6338 kbps 1053 kbps
Line Attenuation 51.5 db 28.2 db
Noise Margin 7.9 db 7.1 db

Very good stats for your attenuation!

Are you on O2 LLU?

EDIT: Have you installed the latest firmware on your DGN2000?
I've got a brand new DGN2000 sitting next to me that I picked up for a neighbour just today...

Well good stats are a good start

Yes O2 LLU, and yep got latest firmware.

Hi

I also have DGN2000 and had similar problems. I realised that it was overheating due to poor ventialation. With the vents all located underneath I decided to prop it up on some legs I made out of some cardboard. Just an inch or so long should do iit. After that no problems whatsoever.

Other ways to improve connection and even speed is by spoofing your MAC address on the DGN2000 with that of your original o2 wireless box. I cant remeber if this is an option on the original firmware though so you will have to look.

It should be at the very bottom of the basic settings page. You can find your o2 wireless box MAC address stamped on the bottom of the box.

If the option isnt there it can be enabled by downloading custom firmware from this site http://dgteam.ilbello.com/index.php?pid=17. I would highly recommend doing so anyway as it also allows some advanced tweaks. Most of which I would leave well alone but under a new page "Advanced ADSL Settings" you will find a slider labelled "SNR Percentage" slide this down by 10% and apply the setting. The router will resync. Now check out your stats on the "Router Statistics" page and check your downstream and upstream stat. Go back to SNR Percentage slider and reduce by a further 10%. If you continue to the repeat the process you should notice your downstream increase as you decrease the SNR Percentage. Until that is you reach an optimum level. Afterwhich you will experience a decrease in downstream. When you notice the downstream decreasing go back to the previous level the SNR Percentage was set at. DOing this I managed to squeeze out an extra 1000kbps at least.

Hope this helps.

Is this related to the DHCP problem that O2/Be customers have when using certain Netgear routers?

I'm sure someone can point you in the right direction if it is.

Thanks for that Dawgsday, i have some spare "feet" off my DG834G so will try that, for cooling

I may try the MAC spoof to thanks, the option is there in the settings, so thats easy to try. As i say it weirdly dosent drop sync it seems just a split second to loose the WAN connection >

Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time
WAN DHCP Client 2945881 3898291 0 493224 104373 00:29:05

I have been surfing around generally for last hour and only noticed a webpage freeze for a few seconds, which presumably was the point it lost the WAN as shown above 30mins ago.

I'll probably leave the other firmware for now.
