Wanting to create a link to an access point 500m away. The distant access point is a high quality one, i just need something as the client.

I can connect to it using a cheap Dealextreme high powered RTL8187L adapter with small omni antenna, and get 1-4ms latency which is a good sign.

However after a permanently mounted adapter, and the goal is to be cheap since this is just for home use.

Part of the plan likely involves repurposing an unused satellite dish to help the signal which happens to be pointing in the right direction. Possibilities included using a usb adapter cantenna style, but the fact that usb is limited to 5m means a computer has to be placed directly by the window, which isn't really an option.

The issue is hardware. Another idea was to run a directional antenna attached to the dish to 4-5m extension (through a window) to a client device inside. But this requires a decent length of cable that can carry 2.4ghz Wifi without major loss. And this type of cable appears to be $10 a metre sadly. Of course it requires a directional antenna too.

The most likely, and most expensive option is to use something like a Ubiquiti Bullet or Nanostation where length of cable doesn't matter. At $100-150 though this is obviously on the more expensive side.


So aside from comments on this, Is there anything cheaper than the Ubiquiti Gear? Does anyone know a cheap way to run the anntena extension?

You either want a good link or you want a cheap link. You won't get both.

2 x 5GHz UBNT Locos are by far your best bet, no reason why you won't get ~70Mbps over that distance.

Without researching all of the details... get something cheap that will run DD-WRT - like a D-Link DIR-600 which can be found for less than $90...

You'd probably have to do a bit of hacking as the antenna on these isn't removable.

Have used similar in the past, but generally use UBNT gear now as its more reliable.

I cannot change the access point im connecting to, its a commercial one, high powered omnidirectional i believe.

The Ubiquiti bullet at $100 is appealing but appears to require an antenna to be attached? Is there anything similar to these kind of devices?

The Loco as linked below has an internal directional antenna which would be fine, note this is a b/g unit, if you use a Loco M2 it will go faster as its a b/g/n but this is going to be limited by what the other end is. I presume it belongs to a WISP, or some other provider, they may not let you use your own CPE, maybe you could explain more.

Yes it's a WISP. And they are running G only. Its a publicly accessible and you can use whatever equipment you like

Hi, well then just go for the Loco as linked above, it also can be run as a NAT router, ie bridge on the wireless(WAN) side and natting the IP the WISP provides on to the wired side (including DHCP server) so you can run your network and multple PCs.

I just got a new DIR-615 Rev E4 last night, I couldn't get DD-WRT to load even though it's supported. My older Rev C works fine with DD-WRT. Fortunately as a WAP/switch the built in firmware works fine.
