Eircom broadband constantly disconnecting.

kingbob387

My Eircom broadband has recently started disconnecting every 3/4 mins...

Does anyone else have this? 'Cause I know my friend that lives up the road has the same condition. I rang Eircom support earlier on today, they did something to my line and restarted my router, but that didn't help at all, the problem just came back few mins later... Again, does anyone else have this condition? I live in Portmarnock, btw.

zyxel router yes?

kingbob387

No, the Netopia one. Model 2247-02.

I doubt it's the router's fault, since I haven't touched it at all.

What are your line stats? Often disconnections are a sign of low snr. It is possible that your speed has been pushed up and your line is not up to it.

Line State Up
Modulation DMT
Data Path Interleave


Downstream Upstream
Max Allowed Speed (kbps) 4096 384
SN Margin (dB) 8.00 29.00
Line Attenuation (dB) 37.50 23.00
CRC Errors 0 2

Sounds like there's a higher level of ambient electrical noise in the area which is dragging down your signal margin to lower than it should be. Attenuation of 37.5 dB should be able to handle 4 mbps no problem.

Could you find out at what times it happens at, and see if it ties in with any other event? Like lights switching on outside or else a timer switching on for immersion etc.

kingbob387

It happens through out the whole day, and I don't seem to find anything that ties with it. :S

Can phones disturb it? 'Cause I just got a HTC Desire, and before that the connection was fine.


I just found out one thing too when looking at the router's page, the SN Margin for downstream keeps going up and down everytime I refresh, lowest I've seen is like -2 highest 11.
Does that matter or it's just natural?

lucernarian

Yeah, the Signal margin should change somewhat each time the page refreshes. If the signal margin changed by more than 3dB in the space of a minute, it would suggest that there's some sort of intermitent electrical noise nearby or less likely, that your modem is starting to fail or that there's a problem with the DSLAM in the exchange. I could be missing something but I can't think of what else.

Have you tried to upgrade the firmware of the netopia? I've seen somewhat increased stability with Netopia 2247 routers when they got a firmware upgrade. http://broadbandsupport.eircom.net/download/netopia/firmware/2247NWG-firmware.bin and a search for "firmware" on the eircom.net support page will show you how it's done.

kingbob387

Yeah, the router is already at it's latest firmware 2247-02 (nwta770r6.bin), updated it long time ago. So is it time for me to get a new router?

lucernarian

There is a slightly later firmware on the eircom website but I doubt it would make much difference to the one that the Motorola website offers.


I wouldn't do that just yet. Nagging eircom to do something would be good. Disconnecting everything from the main socket (extensions and all) and using the modem on that may help matters, and eircom will probably tell you to do something like that anyway. But temporarily disconnecting extension leads and other sockets at the master socket can work wonders.

Had a similar problem a coupel of weeks ago, a few weeks back the original Netopia modem I had went faulty, eircom sent out a new Netopia (same model you have) and I started having the same type of problems you describe (wife driven mad as she works from home and needs the BB).

After a fair bit of tooing and froing, they figured out that the old power supply from my original modem was not fully compatible with the new modem. Changed the power supply to the one that came with the new modem and no problems since !

Felt a bit of a muppet since I was the one who reused the old power lead though they said they would add it to their FAQ list as a few people had the same experience

i have tested the snr thing on the phone with eircom a few months back to try and find the sweet speed for my line..

when the speed is set to high for the line the SNR drops very low, and you get disconnects. your sn margin of 8 seems too low, get your line switched back to 3 mb and you will have a Higher snr value and less disconnects. it looks like your line cant take 4mb ... when my line was set at 7mb i had very low SNR it varied but went as low as 1 or 2 and got frequent disconnects,,

There is something wrong with Netopia modems as Eircom had to replace so far 4 modems that I know. One at home, 2 at work and one of my colleagues is getting new one for his home broadband too. Guessing by the behavior of the modem it is probably a faulty capacitor ether in the power supply or inside the modem that goes faulty after approximately one year of exploitation. So don't suspect your telephone lines or anything else before you rule out the modem itself
