Can i boost wifi network using a netgear fs605uk hub

Thats just a switch - NO wifi on the device

Netgear FS605 Platinum Series 5 Port 10/100 Unmanaged Switch

So NO you can not use that to boost wifi

use xirrus to monitor the wifi signal and see if you can pick up a signal on the other side of the walls - you can get wireless access points WAP , which will extend the wireless signal and also provide Ethernet cable outputs

------------------------------------------------------------------------
Run Xirrus Wi-Fi Inspector Download and install
Xirrus: The Leader in High Performance Wi-Fi - Advanced IT Wi-Fi Networking Tools
Direct link to the program is here Xirrus: The Leader in High Performance Wi-Fi - Advanced IT Wi-Fi Networking Tools
Then run and install the program
if you get an error - You need NET Framework installed for the WiFi Inspector to function.

Run the program

Note:
For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better.

probably not - it will depend if the router allows for WAP mode - you could connect with a cable and extend - but not sure thats what you want - see below connecting two routers

you may be able to put a different firmware onto the router - I have never done this myself
www.dd-wrt.com | Unleash Your Router -
But you will need to know the exact model revision level - as some version you can install firmware , other are a no and some are a WIP
the revision should be on the label on the router
have a look here for which revisions will work

Connecting two (or more) SOHO broadband routers together

Connecting two (or more) SOHO broadband routers together
From a JohnWill post

Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

Disable the DHCP server in the secondary router.

Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!

This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).

For reference, here's a link to a Typical example config using a Netgear router
