Netgear DG834G can't get IP address after factory reset??

I've got an old netgear DG834G router whic has given me faithful service. However I'd begun to notice a lot of buffering and waits so I rang my provider up to see if anything was the matter their end. During the course of the chat they told me to do a factory setting reboot. After doing this the router fails to find a IP address.. Occasionally it does but win 7 still reports Network - no internet access and I can't get online. Shortly after it'll lose the IP address again too.

My provider is suggesting getting another router to test but I'm unsure that it could be that? It was working (all be it slowly!) before this factory reset and yes it is old but could it be that it's broken? Any ideas guys? Could a factory reset have caused this?

Internet light comes on fine btw and my login and password are entered correctly.

Could be the power supply. Netgear PSUs have a bit of a reputation.

Thanks for the reply.
Thing is it turns on fine? Internet light blinks orange, then stays a constant green, as normal. Surely if it was a power issue it wouldn't even turn on?

If you have reset to factory defaults you will have to configure the internet connection. Have run the connection wizard on the routers web interface

Hi mrSaffron, yep run the connection wizard and entered everything my ISP told me to do. It all checks out, I can see their downstream (20114 Kbps) and upstream (1087 Kbps) connection speed, set the vpi to 0 and vci to 38. Entered my login and password etc.

But under router status it refuses to show an IP address?? Sometimes it does if I select 'test' in basic settings an IP address does appear. But my pc is not noticing it and still displays the yellow triangle and !. It will then promptly lose it again and display nothing under IP address.

I just don't get it? Could the factory reset have broken the router? I'm worried I'll go out tomorrow and rush buy a router but get it home and find it doesn't work either! I'm desperate to get my net access back for work.

Out of interest is your isp sky?

No phone coop.

Get rid of it. I had one and noticed that the light was flashing madly when no one in the house was using. I went on to the forums and discovered that this router was easily hacked. Very easily hacked. As it happened I was soon to change over to BT Infinity 2 so I was supplied with a HH5. I did a bit of sniffing round to see who could have broken into the router and I suspect that it was one of my neighbours. I couldn't understand why it kept happening as I kept changing the user name and the password without stopping the hack. A few months later thinking about it, I realised that I had not turned off Wi-Fi while I was changing the passwords and was probably being watched as I did it.
I repeat, bin it. There are plenty of good routers around for just a few quid.

I too have the Netgear DG834G v3, and have been using it for well over 5 years now with no problems. I am on TalkTalk Simplybroadband, and am over two miles from the exchange and getting approx 3.09 Mbs download when I now checked the speed.
I realise I am not offering a solution to the original posters problem, but I would say that I consider the router is still an excellent piece of kit and hope that he finds a solution to his problem.

Is the DG834G the same as DG834GT.

I've been using the latter for several years, so far no problems apart from an occasional (every 4 months or so) drop out of the Wireless Access Point - I just disable the WAP and re-enable it and it's fine for the next few months.

I too use one of these excellent routers but I have spares too so whenever I am suspicious of the router playing up I swap another onto the connection. It has never actually cured a problem though but is a very useful diagnostic step.
It looks to me as though you do have a solid modem sync with the exchange but cannot login to the ISP.
Reasons for this can include :
Modulation mode wrong. Is it Multimode? or ADSL2+ if that is what you have.
PPOA/PPOE settting incorrect.
Get automatically from ISP, ip address and DNS servers not set correctly.
Noise on the line, particularly on the higher frequencies of the Tx side which on my router cause the PPOa session to drop while still leaving the modem synced.
An ISP side problem preventing you from logging in.
A router fault or a weird firmware corruption during the factory reset.You could try another reset and/or a firmware reload.
And I suppose an internal house wiring issue. Have you tried it in the test socket to eliminate this.
Do you have a save of a good working configuration to reload ?
I am no ADSL expert but would try most of the above in your situation.

The quickest way out of this is to try another router first.

I think you replied to me as the last poster rather than the original poster. Nevertheless a useful list of things to try as an aide-m�moire.

Sounds like it's syncing with exchange but not authenticated to ISP.

You mean an external public IP? Then check your BB Username & pwd.

After all with most routers (except O2/Be) a factory reset will reset all the BB paras to standard except for BB Username & pwd.
