My Wireless Network Doesn’t Work When the Baby is Sleeping

Having a baby could affect your wireless communication?

Yes. Well, indirectly yes. Who has a baby and a wireless network will most likely have a baby monitor. We all like to spend our time blogging, or browsing the Internet while the baby is asleep, but we couldn’t blog a word if we didn’t keep an eye on the baby.

Many baby monitors will interfere with wireless networks. The wireless connection will work for most of the time and then suddenly it will stop working; after a wile will resume functioning properly. It could work without interruption but slow down transfer rates as network error corrections will be needed more than regularly.

How TO Eliminate Interference Between Baby Monitors and Wireless Networks?

Make sure you verify the band used by the baby monitor is not overlapping with the wireless band. If it does, you can change the channel on your Baby Monitor. How do you know if it overlaps? Read the instructions manual, and if you don’t have it, just try different channels on your baby monitor until you get a stable connection on your Network.
Another option would be to change the channel used by your wireless access point. If you have an old baby monitor consider buying a newer model, the newer models have less interference with your WiFi Network. I know that this sounds so un-green and consumerist, but I tested this and newer and more expensive models are better protected to interferences.

Is your Toddler Curious about the Little Box on the Wall?

If your child is a toddler he’ll be very curious about the different devices hanging around in your office and he will find your wireless AP. They will try, whenever they have the chance, to press any buttons and pull all the cables. Make sure, when your connection goes off, to check all the connections to the access point and to the modem. Consider to move your devices where your child cannot reach them.

How to make a Loopback Cable

Why do I need a loopback cable?

Sometimes in order to test a computer’s hardware or software we need a network link for the network adapter. The solution, very often, is to carry around a hub. A loopback software adapter sometimes could help but in many cases it doesn’t work.
The best solution is to create a loopback cable. The loopback cable will work as the computer was connected to a real network transmitting and receiving packets. The packets are sent and received in a loop, this kind of setup allowing the technician to troubleshoot hardware.

What is a loopback cable?

A loopback cable redirects the output back into itself. This effectively gives the NIC the impression that it is communicating on a network, since its able to transmit and receive communications.

How to make a loopback cable

The short description for a 100T base Ethernet loopback cable:
Redirect Pin 1 to Pin 3 and Pin 2 to Pin 6.
The detailed explanation with pictures follows:
Materials needed:
Good quality Crimper
Cutter pliers
RJ45 plug
Utility knife
UTP cable
Tools needed for crimping
 
Cat 5 Twisted Pairs Take a CAT3 or CAT5 UTP cable and strip the jacket trying to preserve the jacket intact, as you will need it later.
Maintain the wire twists as this will prevent electromagnetic interferences between the two pairs. Untwist the least possible so you could insert the wires into the RJ45 plug. For a 100T base loopback you only need two pairs, I choose orange and green pairs.
Bend the orange pair at the middle making a U shape.
CAT 5 twisted paires

Insert the Orange pair as follows:
White-Orange wire into the pin number 1 and pin number 3 and the solid Orange wire into pin number 2 and pin number 6. Try do insert the four ends at the same time as this is easier.

Crimping the cable

At this point you can crimp your plug for a 100T base loopback cable. Make sure you insert the cable jacket before crimping. The jacket has to be inserted into the plug about an inch so that it’s crimped in and offers rigidity to the loopback cable.

If you want your loopback cable to work at 1Gb you need to insert the second pair, (green), insert the cable jacket and only crimp after that. The green pair is inserted as follows: solid-Green wire in the pin 4 and pin 8 and white-green into 5 and 7.

How to Troubleshoot Internet Connection Speed

Who didn’t have problems with the Internet speed at least once? OK, many of us, but as an IT professional I always meet and talk to the people who did have problems with their Internet Speed.
