This is getting annoying. It started last friday, and has been on/off since. I know it may be temporary, but I noticed I like my web surfing a lot better when the internet actually works.

Anyway, the modem shows all the needed lights (internet, adsl, sys, power, and the connected LAN), but the connection keeps dying. It works for a minute or two, then dies off. Then it reconnects, works for a few minutes, dies off. Rinse and repeat. Yesterday it actually worked for the whole evening, many hours straight. But then it reverted back.

I called to my internet provider, and a robot answered to me. After spending half and hour listening to its monotonic voice and yelling at it, it threatened me with a 100 euro compensation fee if a maintenance guy comes over and tells me their connection is fine.

Is there any way I can make sure that the problem is not my hardware? I have tested this with two machines, two modems and two phone cable thingies. All have the same problem.

Ideas, suggestions? Call to my internet provider is not doable at the moment, as they seem to have shunned their customer support and there are only robots there...

Most ISPs that I know of have a page where they show the status of their service and give general updates on whether anything is going on in certain coverage areas for free. I don't know if your ISP does that but surely they have a page you can visit during those times your internet is working?

not your computer then. if it happens with other machines (try to get more. if a friend has the same isp use his modem, use laptops) then the only reason it might be your fault is that cables inside walls or in the garden are damaged.
outside your property its their problem.


can't they test from their end. ISP in australia and poland did that for me. they send signal and they can monitor where is the disturbance.

I've had a very similar issue two times already, and on both these occasions it was my ISP. This, of course, doesn't necessarily mean it'll apply to you too - and god, wanting 100 euro if maintenance guy comes and doesn't do anything, seriously...

Log on to the modem status page (usually one of the 192.169.xxx.xxx addresses) and watch the status when it's having a period of trouble.

Are you using a router? If so, take that out of the picture by plugging straight into the modem. Might not be convenient depending on how the provider wires things inside the house.

It's a bit of a pain but you can eliminate your home's wiring by connecting at the point where the service enters the home. For us, on DSL, it's at the phone company box attached to the wall outside the house.

May i ask :

What type of modem do you have ?
Have you tried to turn it off and on ?
Posted September 09, 2012
You are not very specific about your problem, it could be any number of things.

If you are just getting a lot of 404s and disconnects you can just try to flush your DNS cache and see if that helps. Try running "ipconfig /flushdns" from a command prompt. Then try pinging a website and see if it's dropping packets along the way. "ping google.com" for example.

If it is dropping packets, you may want to check where, so "tracert google.com" and see who is dropping the ball.

All this crap may or may not help you if the problem is on your side, but is useful to have the information when calling your ISP tech support, that is, if they ever pick up the phone.

edit: And i just realized it's sunday and their tech support is probably sleeping it off. Damn lazy bastards.

Modem is telewell's TW-EA501. Yes, I have tried turning it off and on, many times. It does not help.

Am I using a router? Erm...what? There's this hole in my wall, a phone cable goes into it. That cable then goes to my modem. Then my computers are connected to the said modem. It has worked like this for years, and now it just started this.

Flushdns does not have any difference.

The ISP home page does have a page for current errors, but guess what? it doesn't load. Or work. Ever.

The modem log tells me that:

Sep 9 16:24:09 IGMP Proxy: Request to send Version 2 Membership
Sep 9 16:24:09 IGMP Proxy: Received Version 3 Membership Report /join group

there are countless of those, and then it says

Sep 9 16:24:22 DHCP SERVER: DHCPINFORM from (ip address)
Sep 9 16:24:25 DHCP SERVER: DHCPINFORM from (ip address)

I didn't include the ip addresses, because I am paranoid and I don't see the relevance.

And the tech guys, well, they don't have a number I can call for people, only for the god damn machine! I hate you Sonera, why don't you care about your customers?

i'm thinking there is a line issue

Knee, turning your modem on and off won't work.

What you have is a dying modem. To get it to behave until you get a modem replacement, you have to power cycle. You need to shut your pc completely off, and completely unplug the power from the modem for 2 minutes.

Power the modem back on, wait for all the lights to fire up, and then when it's completely on, turn your pc back on.

This is a make-shift fix until the modem gets replaced.

That is a good theory, but..

I have another modem, brand new. It doesn't work either.

Okay, this is weird. I changed the modem to the newer one and plugged the ethernet cable into the third lan port thingie. The guide told me that ports 3 & 4 are bridged (whatever that means) and that they do not have a modem firewall on.

Now it seems to work, at least momentarily. Could be a just a fluke or a coincedence. Does it matter what port my computer is plugged into?
Posted September 09, 2012
I've had lose LAN cables cause that kind of thing. If your modem lights are as they should be, it's unlikely to be your internet provider (though their DNS servers could be going down if you're using those).

Check your shit. Also, those consumer grade Linksys routers that cost 30 bucks, those are pieces of shit, they don't last forever, you usually have to replace them every 3 years or so. If you spent good money on a better router this is far less likely to apply.

I'm rusty on this term, most routers don't have a bridge connection, I'm pretty sure that's a direct pass through and you likely don't want to leave your comp on a bridged connection to the internet.

Well, according to the ISP help page, the router is supposed to be kept in bridged setting. That begs the question of why did it work before then?

I am so confused right now..

Generally, it's 192.168.0.1 . Any other of the addresses (192.168.0.2, 192.168.0.3, etc) are all generally computers on the network.
