access points

I use it on the linky bridge
the signal strength and link quality are increased by 8-10 percent point
then I found this antenna works better on single antenna device, on 2 antennae device, it may have problem

update: this antenna works very well with SMC wireless router (used as ap) now, the result is good enough to get a stable connection with MS MN-710
however, for further upgrade, I put an order to get 15dbi directional, in order to connect the forth-coming dell axim x30, since the kitchen is blind point, and the router is located at the edge of the house, a directional antenna can "fire" the signal throughout the house
for SMC 2804 users: connect the antenna at the connector near LAN jack (which is the REAL antenna jack), this helps

I bought this antenna to add to a Linksys 802.11B router that has an extremely limited range in my house. I like to sit with my laptop in the living room about 30 feet away (3 walls between router and computer) and the signal is so low that the connection keeps getting broken and data transfer is slow when the connection is able to keep active. This antenna increased my signal strength from approximately 0-10 percent to about a 30-40 percent level. This is strong enough to never drop the connection and to maintain the full 11 Mbps data transfer rate. Oh yeah, as another reviewer already stated, the picture is wrong. This is an antenna, not a bundle of cable.

First of all Amazon's picture is wrong. This is an antenna and not a bundle of coax.

Before I got this antenna I would lose the signal every 5 minutes in the basement. Now I never lose the signal in the basement. I bought it so that I'd have a reliable connection in the basement. So I'm quite happy.
