Intermittent connection issues are very difficult for internet service providers to trouble shoot. The first step in trouble shooing any Intermittent connection problem is to look at the chain of equipment involved in flow of data from the internet service provider to the end user. In most homes the packets enter from the main line to the modem, than from the modem to the router, and finally from the router to you computer. So that means that the issue can be caused from the following equipment: main cable line, splitter, modem, router, or the Ethernet / wireless card of the PC. The first step in trouble shooting this problem is to wait for the internet to drop off. As soon at this happens go to your modem. If the top 4 lights are not solid green then the the modem is losing it's connection to the internet. This can be cause by some thing as simple as a bad splitter in the home or some thing as complicated at an issue at the pole. If the modem drops the connection I would recommend contacting the internet service provider and demand a service call to swap the modem and check the pole. Now if when the connection drops the modem still has access than the issue is most likely with the router or PC. If more than one computer loses it's internet access than you can rule out the computer as the issue. At this point I would have to recommend bypassing your router for about 48 hours. If the issue does not return than you know the router was the source of the problem.

I hope that information above has helped is some way.
If possible please rate this solution.

My router keeps timing out


One of the things to check first, is IF it's your ISP, your internet provider. Many of them will close connections or set you to reset your DHCP lease frequently. I noticed you did say it works fine to the modem. Does it work fine to the modem for extended periods of time? Or does the same thing happen eventually? I have a routine I run if an ISP drops bandwidth or connection if your inactive for too long, or you can call them and demand a longer DHCP lease time if that's the factor. Many cable and router companies don't even check this before they start replacing equipment such as modems or routers. IF the same thing happens when you stay connected to the modem from the computer directly for say a whole day, then we have to start looking at other potential issues. I am following the problem. Feel free to comment or whatever. I will check back frequently. If you would like to work through this problem I will assist you. It will take troubleshooting and a few steps. It's just not that simple with 1000s of things that can go wrong. This computer/Networking stuff is not Rocket Science. If it was we would never make it off the earth as broken/unfinished products are shiped and sold daily. Software is flawed. You have about 10 different corporations with nothing but profit as there motive involved. Feel free to contact me or we can do it here as well.

Since getting a new Dell laptop and Linksys E1000 (also have HP desktop), my internet connection keeps dropping (no problems ever before)- sometimes I can stay online for 2-3 hours or it can go in 15...


Hi,

we need to first figure out whether it the modem or the router which is dropping the connection.

Please connect one of your computer directly to the modem, by pass the router and access the internet. If the connection drops then its the modem which is dropping the connection and you need to contact your isp to check it.

If the internet works fine directly with the modem then its your router which is dropping the connection. To fix the router we can upgrade it firmware.

To upgrade the firmware please visit the link below;

Note; If you are not comfortable upgrade the firmware then don’t do it. If not done properly then it can damage your router.

My internet keeps dro, i have installed filters ,


There is one case where everything is fine but still connection drops too often.---
This happens when the network type of your laptop is "public" as ublic networks are less secure, routers usually drop connections after sme time. Change the network type to "private". This should solve your problem. There is one more setting in your router where is says something like "automatically login when disconnected". Selecting this option allows automatically login to ISP when connection is dropped from ISP temporarily.

If network connectivity itself is the problem then you can debug followingly.

Step-1:
If ISP company says everything is fine from their side, then you need to check your router. To confirm this first connect the wall outlet of ISP to your laptop and check network connectivity. If there is problem, then ISP has to fix it.

Step-2:
If connection works fine then ISP is fine and you need to check your router settings. Now check network connectivity by connecting the laptop to the router through a ethernet wire. If the network does not work then your router hardware could be wrong and may need servicing or replacement. If this works fine then go to step-3.

Step-3:
Try resetting your router by using a paperclip. Usually the reset button can be found at the backside of your router. This will reset all the settings and there by making as good as a fresh one. Try to access internet from a place close to router where router signal is strong.
Change authentication and other network settings of your router to connect to ISP. Now network should work fine. Ensure that you set router password to avoid unauthorized access to your router by others.

Connection Interrupted on Xbox Live with COD


To me it sounds like you are having a DSL problem. If you are not up to calling your ISP for a trouble call, try playing at a friends house with your console and see if the problem happens there also. If it has no problems, then you know your console is not the culprit. You could also try connecting directly to your modem and bypassing the router for testing purposes. If a direct connect to modem works, then look at your router.

Linksys is PnP with Live. You should not have to open any ports. If you get to the point during troubleshooting that you know for sure it is your router, reset it to default settings.

My modem keeps losing internet connection


Update your drivers and then do a speed test. Most isp send updates to the subscribers when they update, yours may not. Don't forget to check all of your connections before wasting time calling your isp. I trust this test the most. Rember you don't always get what you pay for.

One simple solution, can you try using the router on another ISP connection (at your friends' place possibly?) This will rule out the possiblility of your ISP fault saving you $65 straightaway...

Every time i go onto a server on counter strike source i get this little box that says client timed out and my steam which runs my counter strike source is disconnected


you could have a few issues here, one being your modem, your firewall or your isp speed. Try rating your isp with a speed check, see if your operating where you should be and get back to me.

Getting disconnected from the net


hi marco22,

first thing you need to do is contact your Internet Service Provider (ISP) for them to check the line, because there is a posibility that it could be a problem from your ISP.

if everythings OK from your ISP end, better enable first the keep-alive option on your modem, if possible to upgrade the software of the modem do it first, before changing it.

and better called the manufacturer for the modem to make sure that your are doing the right thing.

have a great day ahead.
