Wirless 7dbi Antennas dont increase signal

[Sl33py]

Good day
I have a Netgear router in the basement, the wireless signal is strong enough to reach the top floor and cover most of the house. We want to extend the network the flat behind the house.
Outside the flat I pick up the Netgear but not strong enough to connect

I configured a Linksys WRT 54 GL with dd-wrt and configured the router as a repeating bridge.
I placed this in the middle of the house opposite the flat I can connect to the Linksys and at times surf the net but the signal gets dropped

I then went and got 2 * 7dbi DLink antennas one for the router and one for the pc in the flat hoping that they will be strong enough to bypass the Linksys and work as is ( a Supplier assured me this will work, it did not) I have tried both antennas on the Linksys no increase. I have tried different combinations no luck.

The only thing that helped was if I plugged one antenna into the PC in the flat and then stuck the antenna outside the window. We don’t want to drill holes if we have to we might as well lay a cable

Both antennas can’t be faulty?? What am I missing here?

Check in the router if you can't maybe change the antenna strength? Our school has a HP ProCurve access point, and in there we changed from 2dbi to 7dbi when we got new D-Link antennae. It worked, because the signal is much stronger.

Hope this helps

The antenna’s got a “sweet spot” the signal has a 24 degree window I played around with bending it and got the signal better, t is not dropping it anymore.

What you can also do is to do a scan of your area. That will show up and signals already in your area. Now you can select a frequency that is not used by anybody else around you. That should also increase your speed and signal.

What is a good program to do a scan with?
