The ADSL modem drops connection and screws the network

post #1 of 9
Thread Starter 
Hey guys! So I've been having this problem for a few years now and now I realised I could ask about it on my fav forum OCN!

My old ADSL modem Zyxel P660-HTW occasionally drops connection and because of it the whole network (all the PCs, laptops and other devices) goes down for the period while the modem reestablishes the connection.

Problem is that there is no way I can improve my phone line. I live in the countryside and my house is quite a few kilometers away from the exchange. Also the line itself is old and worn off. I already somehow got used to it.

But the question remains, is it the deal with all the ADSL modems or it's my particular network that drops the whole network during restart? I was wondering if someone could suggest a way or a new modem/router for my network (got quite a few devices which have to interract with each other constantly)? For instance, I and my brother can be playing CS or anything on LAN, but if the inet goes down (although we're not using it at that moment) then we get a disconnect as well.

I hope I didn't make it too confusing. I am noob in networking and have no idea if that is possible or not to arrange.

Actually while typing I thought of one way.. Should I get a separate router and bridge it to the modem? Will that fix my problem (network going down)?

Thanks in advance to those who would take his time to read my wall of text

I run with an ADSL modem in bridged mode with a router and I've never had that problem. But about every 6-8 months my modem will take a crap and it usually needs replaced to permanently fix the problems it causes (dropped packets, sometimes dropped internet connection). Stupid AT&T and their stupid modems...

In your case, running with a router/modem in bridged mode should keep your network up while internet connection is down.

I'd get a replacement device.
Your entire environment should not be affected by the ATM interface resync'ing with the DSLAM.

I am pretty sure it was always like this with this ADSL modem. I guess it's coz the modem is quite old. So the newer ADSL wi-fi modems don't drop the network connection between devices during resync? If so, I would rather get a new one. Coz right now I was looking into routers and planning to bridge it with the existing ADSL modem in order to make the network never drop.

This is what I would recommend if you don't want to spend a lot. Just bridge the modem/router you have and get a good router.

I'm sure there are good modem/router combos out there, but I always keep them separate myself. It just seems to result in less issues.

Just my 2c worth,

Rich

Yeh, thanks again. That's what I am planning to do. Any good router that you could recommend? I might be willing to upgrade the firmware to dd-wrt or similar later on for awesomness!

I highly recommend any of the Netgear WNDR series.

I have the 3700 both at home and work, and they are both trouble-free. I have heard good things about the 4000, but haven't seen it myself.

Also, should you choose to go that route, the 3700 is listed as dd-wrt compatible.Just my 2c worth...hope it helps,

Rich
