How many Airports can I use on my Wi-Fi network?

Episode 1112

Chris from Miami, FL
Wi-Fi

Chris has a Wi-Fi issue in his house, and he's been told that he can only have three Airports in his home because it would cause problems. Leo says there shouldn't be a limit with WDS if the other Airports are just passing along the data and extending the network. If they're all on the same channel, then the limit will probably be in force since collisions could occur. The trick is to get the channels that are overlapping as far apart as possible, around 100 feet away. This is to reduce Wi-Fi congestion. It can work, but it could be a bit less reliable.

How can I stop my computer from losing the network?

Episode 1108

Michael from Long Beach, CA
Ethernet cable

Michael has a computer that drops off the network from time to time, causing him to restart either the computer or the router. Leo says it's probably not the router since other computers aren't effected. If a computer drops off the network, then there's probably an issue with Mike's ethernet card since it's wired in. He should first replace the ethernet cable. That's the cheap and easy fix.

How can I extend the Wi-Fi signal from an Apple Airport Extreme?

Episode 1106

Jeff from Los Angeles, CA
Apple Airport Express

Jeff has a 3000' square foot house and has several Apple Airport Expresses to relay the signal from his Airport Extreme. Leo says that Jeff should have the Express in 'Bridging mode' and should let the Airport Extreme choose the channel because it will adjust according to congestion. Just select the option to extend the network and let it handle everything else.

What cable should I run through my house for fast networking?

Episode 1094

Fred from Upland, CA
Cat 6 Ethernet

Fred is remodeling his home and he's got open walls right now. What cabling should he install so he's set for the future? Leo says he should install Cat 6 Ethernet cable. That would really future proof his home with fast data networking. Or he could just go with wireless networking. He should at least run conduit in the walls and as the technologies change, he can then reinstall whatever cable he needs. Fiber optic cable is pretty cheap, but the switches are expensive. That's why Ethernet is still the best way to go.

Should I use Watchguard for my Wi-Fi network?

Ken from Toronto, Canada

Episode 1081

Ken is wondering if he should use Watchguard on his Wi-Fi network for added security. Leo says he doesn't need this. These are internet security devices, or firewalls, that he'd run in his house. Routers are not very well designed and are commodity products, so they tend to have security flaws. Getting a better router would be a better way to increase security. Leo suspects Watchguard would be more than he actually needs.

Why can't my wireless camera connect to my server?

Walt from Huntington, WV

Episode 1068

Walt and is using an old server as a home computer. He uses Alarms.com to monitor his home security system, and it works wired. But when he changes over to the wireless configuration on the camera, one of his cameras will not connect.

Leo says that there may be a DHCP conflict that's preventing it, or the password based security is the issue. He should try turning off security on the router to see if it works. It may be the older camera can't be supported with the newer security standard used by the router.

Why can't my Mac print to my wireless printer?

Ray from Tennessee

Episode 1063

Ray has a friend who just bought a MacBook Air and he's having trouble connecting to his Canon wireless printer. He can print when it's hardwired, but not wirelessly. Leo says that he's used a Canon Pixma wireless printer for years. The question is, will it print with any other computer? If so, then it isn't a network issue. Leo says to remove the printer and then add it again. It may have had a problem when it was first added. Leo also recommends using the Apple drivers as opposed to the separate drivers from Canon.
