Erratic Wireless connections

I setup a wireless connection between my house and the barn. The bard is about 100 yards from the house. I have two computers both running Windows 7. I am using at a NetGear WNR3500L Router and a wireless pci adapter in the barn and attached a Hawking HA12W HiGain Directional 12dBi Window Antenna to it. I will go 4 or 5 days with no problem and then I will lose my connection. Are there settings in the router I can change to make the connection more reliable? Is there something else I should be looking at that will help?

Thanks!

Robert

Try a firmware update for the router.

However, I've just seen this...

You can try raising your ACK timing a bit (usually its around 2000m though so you should be ok).  You'd probably be a lot better off getting a directional antenna for the Netgear router as well and making sure both endpoints have LOS (Line of Sight) to each other.  Note any obstructions in the way, particularly those with metal or electricity in them.

You can also try and switch channels manually. Use Inssider to see if there are any other wireless networks around and their channels. Change to the least used channel in your area.

The router has the most recent firmware installed and is set to find a channel automatically. How would I change the ACK timing?

I have never set or changed ACK timing so I would really appreciate some help in how to do this. Where do I go to make changes or at least to see what the default setting is? Is this on the antenna or the router?

The wireless works for 4-5 days without a problem, so there is no issue with LOS or TX power from the router.
If you restart the router when you lose connection does it work again?

I'm seeing lots of bad reports about this router with its default firmware.  Many people have installed DD-WRT on theirs which makes things better.

It appears the problem exists mostly when the weather is bad.
