Do not connect between the buildings that far apart using a Cat5/6 cable, you will create something called a ground loop, the wireless option is best and a much simpler installation method all round.

There won't be any ground loop as there is no connection to earth at all.

will a 5GHZ only AP such as the Ubiquiti devices work with the BT Hub3 which is 2.4GHz?

Yes they will work fine, the wifi on the hub 3 has no bearing on the wifi bridge.

If you only require one PC at the remote location then using CAT5 is perfect, but as you have an existing belkin router (hopefully set up as an access point) then use this in the remote building

1) Set up one AP (IP address and wifi bridge settings); without looking at the manual for the ubiquit I cannot help further, but ensure the IP address is outside the DHCP range of the hub3 (below 192.168.1.64 I seem to remember).

2) Set up the second AP

These AP are probably powered by POE over the cat5 cable.

3) Use the belkin AP in the remote building or just use cat5 from the PC directly (via the injector) to the ubiquiti device.

This Belkin is a router, not an AccessPoint. Not even sure it can be configured as an AP. I think we need first to check that at least it can be configured to take the signal from the BT HH3 (to be precise, 'to route' the traffic) ?
5 Ghz has less wall penetration than 2.4 GHz. Stay with 2.4 for that reason alone, unless you have a very crowded WiFi environment. The BELKIN boasts it can do both, make sure you pick up its 2.4, not 5 GHz.

As far as I can see from the manual the BELKIN is a very basic device with hardly any possible settings. A hardware design from 2011 (regardless when it was bought)

Are you sure that any other device can connect to it wirelessly? If you have a VERY slow connection, are you sure it is really coming from this BELKIN?

Also most people underestimate that WiFi problems are hugely influenced by the sensitivity of the receiver, much mor than by the output power of the sender. Is the PC receiving OK if it's in range of a good WiFi signal?

Once these basic checks are done we can start thinking about buying new equipment.

And finally, who set it up this way? Has it ever worked before?

One more: "The standard minimum clearance over every part of the carriageway of a public road is 16 feet 6 inches (5.03 metres)." More here: http://www.hse.gov.uk

It works fine if you turn off DHCP and connect an Ethernet between the two devices.
This applies to virtually all routers.

I use a pair of Ubiquiti Loco M5s to link two buildings - I've found them to be rock solid, fast, and easy to configure. They shouldn't have any problem with a distance where you can see one from the other.

I have a network that currently includes about 20 Ubiquiti's (various models) and have to agree, they are brilliant. Excellent value for money.

Yeah, if anything, for such a short link you'll probably need to reduce the power on them, at full power they are good for links of several kilometres.

The Belkin router does have AP mode and works fine within the building it is setup in.
We do have a wireless signal which varies between 3 and 4 bars depending in which floor and room we are in.

Hi ian007jen,
Having had a look again at the buildings and spoken to the people concerned we will probably go with the catenary wire to take the external cat5e cable from one building to the other as there is enough height.
The setup would be as this drawn a diagram. http://i1304.photobucket.com/albums/s524/scopio1/201... .
I would like advice on whether this setup is possible and what may be the constraints on say the degradation on the signal strengths because of the length of cable if any.
I have tested the speed at the BT Hub3 and is 15.7Mbps with ADSL.
The BT Broadband Availability Checker http://i1304.photobucket.com/albums/s524/scopio1/201... FYI. Not sure why the checker says it is connected to cabinet 18 when I live in a flat directly above where the Hub3 is situated and for me the checker says I am connected to cabinet 2 which is 150m away!

Hi

Cat5e is good for 100Mbps or 1000Mbps at 100 metres so all should be OK.

Looking at your diagram

1) Do the AP's have more that one LAN (normally yellow) sockets?
2) I would change your single faceplate for double faceplates
3) I would put one of these http://www.broadbandbuyer.com/products/27606-solwise... (earthed) on both exterior wals

Ian

Yes the existing Belkin AP does have four LAN sockets; the two new AP�s we haven�t yet bought.
You mean a 2 Port Single Socket RJ45 Network Cat 5e Faceplate I would prefer it if possible as long as the two ports can be connected from a single feed and not having to run two separate feeds as running the cat5e cables are difficult enough as it is.
Fitting Solwise WL-ETHLIG-GIG Gigabit Ethernet Lightning Arrestors is a good idea.
I had an idea of what is required but I am not knowledgeable enough of how to achieve what is required.
Thanks for all your help.
