21CN with Dratek 2800


[link to this post]
 
At our office we have broadband direct with Entanet. Several weeks ago the connection started dropping frequently and randomly. This seemed to coincide with our exchange being changed to 21CN. When we swapped our Draytek 2800 router for a Draytek 2800G the problem persisted. However when swapped with a Belkin router the connection was rock solid. Unfortunately the Belkin router does not have some of the Draytek features that we need. Namely support for multiple WAN IP addresses and internal port forwarding. From doing some research on the internet it seems that there are issues with the Draytek 2800 router and 21CN. We have tried upgrading the firmware on the Draytek router but it seems to have made no difference. We have also tried turning off interleaving but the instability was unchanged. We have changed the Entanet service from ADSL to ADSL2+ and changed the stability setting from Standard to Stable and this seems to have improved the situation slightly but we still get the occassional drop and I have noticed that the SNR on the router status page is up around 20+ and even near 30db sometimes. I'm not sure if this is an indication of the line itself or Dynamic Line Management (DLM) seeing our line as unstable and trying to do what it can.

So my questions are thus:
Is it true that the Draytek 2800 is not compatible with 21CN? Surely BT can't just foist 21CN on us and make our existing routers defunct?
Assuming that the Draytek won't work with 21CN can anyone recommend a good ADSL router that supports internal port forwarding (by which I mean if you enter the external ip addresses it will perform the port forwarding even if you are on the LAN side of the router). This is essential for us as we have laptop users who have application settings which need to remain the same whether they are in or out of the office. Ideally the router should also support multiple WAN ip addresses but this isn;t essential. I have seen many people talk about Netgear routers being good but I don't know much about them or if any support internal port forwarding. Any suggestions please?

The 2800 range have had problems with ADSL2+ services for quite a while. However the 2800's worked well on ADSL(1).

The newer draytek kit (e.g. 2820) is vastly improved; and if you're using wireless is finally WiFi Certified.

It might be just that?

Thanks for that. Given this fiasco though I don't see why I need to be loyal to Draytek. Isn't there anything better out there?

I too have a Draytek 2800 and had several line drops and resyncs when I was upgraded to ADSL2+. My ISP reset my connection back to ADSL1 - while remaining on 21CN and the connection has become rock solid again. So maybe it was not the move to 21CN which is causing your problems but a switch from ADSL1 to ADSL2+. Things might improve if you get your ISP to switch you onto ADSL1 (G.DMT).

There are lots of routers vendors; it depends what you want. The features the draytek range have that others generally don't are:
* multiple SSID's on wireless (with LAN isolation if required)
* VPN inbound and outbound - multi protocol and LAN or home worker
* pretty easy to configure web interface
* USB socket for printing (LPR) or 3G dongle for backup
(on the 2820 range the USB socket can also take a USB memory stick for mass storage).
(also on the 2820 range are two WAN sockets, ethernet and ADSL, or dual ethernet models)

If you only want a simple ADSL home router, then worth starting a new thread to get suggestions. Post your existing connection stats as well. (Attenuation, SNRM, sync speed).

The E67.36 firmware works much better with ADSL2+ and would be worth a shot before splashing out on new kit: http://www.support.draytek.co.uk/download/v2800_282_...

I am using the E.67.36.1 Annex A 2.8.2 version and then set the line to ADSL2. This worked for me for around 6-8 mths before I moved to a LLU provider, where again I kept the settings at ADSL2

Thanks for your suggestion. Curiously our experience seems to have been exactly opposite. We were still on ADSL1 and switching to ADSL2+ has improved the stability but not cured it entirely.

I'll look into that. Thanks.
Thanks too iand for the confirmation of your working setup.

Thanks for your post.
We have ADSL from Swisscom and yesterday they "upgraded" our line (np other info provided). Afterwards - no ADSL at all!!!!.

I figured they had screwed up their "upgrade" and spent all day ranting at them down the phone but after finding your comments (I have a Vigor2800) I upgraded the firmware (which was UK 2.8.2 - the latest version) to E.67.36.1 and it then connected perfectly again and has run fine since.

Respect! - You saved me binning my router and buying a new one!

I too have just upgraded a 2800 which I had "filed" a year ago since I got ADSL2+ and it no longer connected. Amazed to find that with the 67.36.1 firmware, the router connected immediately to ADSL2+, so I have brought the 2800 back into service at last!

Good to see your draytek 2800 works on 21CN adsl2+. When I was with Entanet this worked very well, although it would drop PPP from time to time and then autologin again. I moved to the C&W LLU service and the same happened, but from time to time the autologin did not work and I would have to physically reset the 2800 Drayek. I have just "downgraded" to a TD-W8960N router for £50 (with VPN but no VOIP) and this has worked and relogged in without any problems. So you Draytek 2800 users, it does work, but with a few niggles. Some you see some you dont.

2800 does not work for me, fails to establish a firm connection for hours at a time, occasionally connects and holds for a few hours, then several hours failing again.

Upgraded firmware to 2.8.2 before I started so no joy there.

Why would I ever buy another Draytek again, it is clear from this thread that it is not an ADSL2 router and does not get the best of the line.

ADSL2 is supposed to be a 19mb service, 2800 can't seem to operate above 10mb
