I have the westell wireles router/modem in our family room on the north side of the house. We have Fios TV, a computer, laptop, and 2 game systems accessing the system in the same room, which is why we had it installed there.
I have a trailer on the south side of the house with 2 rooms and a garage inbetween. I was successful in extending the phone and Fios TV to the trailer, but the wireless signal is not strong enough.
I would like to be able to use a laptop wirelessly out there as well as the ability to use a printer in the trailer as well.
What do I need in order to accomplish this?
You have several choices.
1). You can run a CAT5 cable out the WAN port on the router to the trailer, and install a wireless access point in the trailer connected to the other end of the Cat5 cable, or
2) You can buy a wireless repeater/ extender device that can act as a relay such as a Netgear WG602 in 'relay' mode or a D-Link AirPlus G DWL-G710 for example.
3). You can try installing a high gain antenna on either the westell modem/router and or the devices in the trailer.
4). You may be able to move the Westell to a 'better' location that could serve both the house and the trailer.
These choice are in order of likely success. I can guarantee you that running a cat 5 cable from the router to the trailer and installing a wireless access point in the trailer will work.A high quality CAT 5 cable should be capable of a 325 foot (100 meter) run.
The odds on getting the necessary range to the trailer via a wireless repeater depend upon what the total distance that has to covered is.
High gain antennae may or may not work, and relocating the router may or may not be helpful.
