ComcastBonnie Happy Fun-Time Learning Series GO!

(I was originally going to post this back in September. Oops!)

Since the new school year has begun, let’s learn some fun stuff about your internet connection and how to fix it! Prepare to amaze and awe your neighbors, family, and friends who will suddenly deem you as their tech support person

OK, class! Let’s begin…

Today, we’ll start off our fun learning series with the simple stuff. When I see problems, the very first thing I’ll ask is: Have you reset your modem? If the answer is yes, then I’ll ask: Do you have a router? This isn’t because I’m trying to blame any particular piece of equipment. You’d be amazed at how many times a router will get “out of sync” with a modem, and vice versa. To fix this…

1. · pull the power from both the modem and the router
2. · Next, plug the power into the modem ONLY.
3. · Wait for the lights on the front to calm down. On Motorola modems, you need four SOLID green lights. (Scientific Atlanta/Webstar needs a SOLID cable light. RCA modems need the Cable Link and Internet light SOLID. If you have a modem not listed here, chances are you bought it or it’s an end of life modem and should be replaced)
4. · Once this is done, go ahead and plug the power back into your router and wait for it to finish up it’s startup sequence.

Easy enough, right? If you’re still unable to connect, try moving on to the slightly more complicated steps below.

For a direct connection to the modem:

• · PC’s: Go to “Network Connections” in your Control Panel. Right mouse click on “Local Area Connection” and click Status. Click the Support tab in this window, and check the IP address.
• · Macs: Finder>Applications>System Utilities>Network Utility This will display your current IP address.
• · Does the IP start with 169.254? If so, your computer is not getting a connection from the modem and you should probably give us a call. If you see 192.168, you’re connected to a router, have your IP set static, or something else is going on with the modem. Again, something you might want to call us up about.

For connections using a router:

• · Make sure your router is obtaining an IP address by going to its home page at http://192.168.1.1 (login required in most cases). You should be able to check on the router’s status page and see if you are getting an IP. If you see a 169.254.xxx.xxx address, your router is not connecting to the modem. This could mean that it was not powered on in the right order OR the modem is not assigning IP’s.
• · Make sure your computer is receiving an IP address from the router by following the steps above. A 192.168.x.x of 10.x.x.x address should show. If not, your router has a problem!
• · Make sure you’re connected to your own wireless network. I get more of this than most people think. Be sure to put your wireless network as top priority over others in your network preferences.

For the super geeks out there:

Speaking of modem’s not handing out IP’s… I see this little problem all the time. The geeks out there seem to notice this the most, and take extraordinary measures to correct the problem. I’ll see folks spoofing their MAC Addresses to get the modem to talk to the equipment on the other end. Guess what? You don’t need to do that ANY TIME you connect something in to your modem, you will need to reset the modem. Otherwise, it will still consider the original device connected, and hence refuse to work with the new device. Easy fix, right? Make sure you’re not overlooking the basics above, since it’s easy to forget the most obvious things sometimes. I once troubleshot a modem for well over an hour, and then discovered it was in standby. The lights on the modem will tell you a lot about what’s going on.

I hope this gives you a little insight into the basics of troubleshooting. Next week, we’ll move on to checking out your internet signal from the comfort of your own home
