Internet disconnects for no reason

[zvit]

My Internet connection can go for days with no problem and then for half a day will disconnect every few minutes. The strange thing is that all I have to do to get it back is to disconnect the cable from my computer and reconnect it and in seconds I have Internet again. My internet provider cannot find a problem with the connection and all assume it has something to do with the modem or router but I cannot find any problem with them.

We have a router with 2 computers connected to it and we have a static IP.

I have no 3rd party firewalls and like I said, most of the week this doesn't happen.

I have read all kinds of solutions and have tried them all (installing router\modem\windows updates, etc...)

Instead of trying to figure out what the cause is, since my solution is taking out the cable and putting it back, thus forcing a reconnection, I wanted to ask if you know of any software that would monitor my internet connection and when it sees that it got disconnected, it would force a restart of the connection (like what I do manually by taking the cable in and out.)

Thanks.

Well, instead of manually taking the cable in and out, go into command promt (Start -> "cmd") and type "ipconfig /renew".

Have you tried scanning for viruses? In one case I had, an infected computer was attempting to attack other computers on the network, disconnecting them from the internet. Use Malwarebytes Anti-Malware or SUPER Antispyware.

 

[zvit]

Yes, I scan my computer weekly. My AV is NOD32 and my weekly scan is with CCleaner and SUPERAntiSpyware Professional. I also do a weekly run of Hijackthis. I will try flushing my connection and if it works, I will make a .bat file to do this but I need someway that the computer could do it for me as soon as the connection gets lost.

Most likely this is a router problem, have you tried updating the firmware? What model of router are you using?

 

[Product FRED]

Yes, out of curiosity, what router do you have?

 

[Jacee]

Have you tried right clicking on the monitor icon in task tray and troubleshooting the connection?

 

[zvit]

Right clicking and troubleshooting did nothing. (come on... you think Microsoft would reveal their bugs??
My router is Edimax BR-6104k. I will go into the setup page now and do a firmware upgrade. Hope it helps.

UPDATE:
Ok, upgraded from 3.25 to 3.29.
Will wait a few days and cross fingers.

I doubt it's an OP system problem although updating the firmware has fixed problems like this on many occasions. If not I would suspect that one of your A/V's might be causing this problem. Hoping for the best.

Nearly 24 hours later still wondering if the firmware update helped or not.

You swap out the network card or add one and disable the on-board one if it's the first network card added?
My typical life for a network card is less than 2 years.

Faladu, the computer is less than a year old but thanks for the input.

Is the connection still getting lost zvit?

 

[zvit]

It did yesterday once and when I got here this morning it was off too. All I did was take out the cable connected to the computer and put it back in and all was good.

I tried that ipconfig \renew but the CMD window said that it can't do that when there is no connection.

p.s. I usually update a post in ANY forum when I have updates or solutions but this is the first time that a user ASKED me if there was any news! Very nice. I was impressed. Thanks.

Ok then here is something new you can try in the routers set up page. You should be able to find a place where you can change channels in the Advanced settings. The default channel is usually channel 6 so you end up with many connections in your area on that same channel which can cause frequent disconnects. Try changing to another channel like 8 or 10, usually makes no difference as long as it's not the one everyone else is using.

 

[zvit]

I can't find such a setting. I sent you a private message about it.

 

[chev65]

Ok I looked over the manual for your router, it's an outdated model to say the least. It's also a wired only router which means it's not a channel crosover problem. Let me check for compatiblity with Windows 7. Your computer is fairly new so drivers should be working ok.

The latest firmware for your router was released 5-15-07 so it's compatiblity with Widows 7 is questionable. The only Edimax router showing support for Windows 7 is the BR-6225N which is a much more modern router.

If you have any type of A/V software on your machine that could cause this problem or if you are using any type of third party networking problem might be an issue also. If you aren't running any of those then upgrading your router might be a good option here.

You might try the firmware update on the page in the link below for your BR-6104K router.

I already upgraded the firmware. The second computer that is connected to this router has XP and gets disconnected when I do. (p.s. today it didn't disconnect yet.)

If you'd like, I'll give you the IP for the router with user and pass so you can see the settings yourself. Of course, I'd send you this in a private message.

I can change the router but I know my boss won't do that. He doesn't care that I have to take the cable in and out.

It's a fairly common requirement to install new firmware when upgrading to a new op system with an old router. Happens here all the time and it's fixed many network problems in the past.

Sorry for the bad link if you clicked it was some lame drive detective. These should be newer than the ones form the manufacture site. Have to scroll down for them.

Others with your model of router are having the same problems.
