How to resolve issues that cause intermittent Internet Connectivity?
Troubleshooting intermittent Internet Connectivity issues.
There can be instances when you have ‘Intermittent’ connections issues with your ISP. This article details some steps that are to be taken to resolve the issue.
In all probability, this is nothing but an Intermittent connection issue with your Internet Service Provider (ISP).
Follow these steps and try to resolve the issue (Note: Order is important).
- Ensure that your TCP/IP settings match your ISP's recommendations.
- Uninstall (just disabling doesn't always work) all installed software firewalls. The generic way of doing this is as follows:
- From your Task bar go to Start > Control Panel. Open Add/Remove Programs.
- Select the Firewall software which you want to remove and click Remove.
- Shut down your PC.
- Connect the cable modem directly to the PC. (Not through a hub, router, switch, firewall etc.)
- Unplug (from power) all wireless equipment (phone, speakers, other wireless electronics) that's within 25 feet of your cable modem. In certain cases, these devices interfere with the cable modem and it will try to read their signals.
- Switch your cable modem off, wait for a couple of minutes, then turn it back on.
- Restart your PC.
- From your task bar click Start > Run > type "msconfig". Click OK.
- The msconfig window will appear.
- Click on Startup. Uncheck the Startup Items box.
- Click OK.
- Restart your PC and try to connect.
(Users of Windows 98 to Windows Millennium: Be very careful when you perform the "msconfig" as it might disable any anti-virus software and/or firewall software you have installed).
The problem is likely to be resolved. However, if the problem persists, try connecting the modem to another PC.
- If you are able to get connected properly, it means your original PC needs some configuration help. Try following the suggestions given in the FAQs or support forum of your ISP.
- Sometimes, your connection could be down. First reboot your modem and computer (and router if applicable) by turning them off and then powering them on. Now see if you are able to reconnect.
- If you are not able, attempt to restore your network connectivity by releasing and renewing your IP address:
- In Windows 9x, go to Start / Run, and type winipcfg. Click the Release All button, then click Renew All.
- In Windows 2000, open a Command Prompt (Start / Programs / Accessories). Type ipconfig /release and then ipconfig /renew.
- In Windows XP, go to Start / Run and type cmd to open a command prompt window. Type ipconfig /release and then ipconfig /renew.
- Sometimes, websites take forever to connect, but then load quickly. This is due to faulty or overloaded DNS servers. DNS servers provide the ability to translate alphanumeric internet addresses (ie. www.broadbandreports.com) into numeric addresses (ie. 209.123.109.175) so that they can be located across the Internet.
By default, your ISP automatically assigns you two DNS servers when your cable modem first connects to the ISP's network on power-up. Many users find their ISP-assigned DNS servers behave erratically and chose to manually configure their own. Here’s how you can manually configure DNS servers.
Note: Instructions below are for Windows 2000, XP and 2003 users only.
To change DNS servers:
- Right click on the My Network Places icon on the desktop and select Properties.
- Locate the network connection associated with your Internet connection. This is labeled Local Area Connection.
Note: If you have more than one connection to choose from, be sure you determine the right one before proceeding.
- Right click on the appropriate connection and select Properties.

- In the list that appears under the General tab, double click on Internet Protocol (TCP/IP).
- Click Properties.
- In the window that appears, select the option to Use the following DNS server addresses...
Note: At this point enter at least one of your personal preferred DNS servers. There are a number of public servers; simply do a search for 'DNS' and you should get adequate results. - Press OK out of all windows until you are back to the Network Connections window. You can now open your web browser and browse to a website to see if it connects faster.
- Right click on the My Network Places icon on the desktop and select Properties.
