Pre setup directions, regardless of what other equipment you have. This assumes that you have a Windows Computer.
#1 Go to http://www.dslreports.com/faq/7553
#2 Download the tool that is addressed in that FAQ. Do not install it at this time.
#3 Make sure that you know how to setup a Static IP on your computer.
a) At http://portforward.com/networking/staticip.htm there is some guides.
b) If your computer has at least two NICs, be sure to which NIC is which.
-- End pre setup - regardless of what other equipment you have. For a Windows Computer.
#4 Your Netgear router has a built in switch in it.
#5 If you have a hub/switch that is not part of a router, this what you do - Otherwise, skip down to (what to do without a hub/switch - not part of a router).
#6 Make that hub/switch is only connected to a power supply at this stage.
#7 Disconnect the wire from the Westell at the Netgear end.
#8 That wire, if I understand things correctly, goes to the port next to the uplink port of that hub/switch
#9 Connect another wire from the Netgear's WAN/Internet/To Modem port.
#10 The other end of the wire that is connected to the Netgear's WAN/Internet/To Modem port, connects to any other port the hub/switch but not the uplink port or the port in use by the modem.
#11 Make sure your computer(s) behind the Netgear router can still access the net.
#12 One of the reasons that I said that in step 11, is because maybe I made a mistake in step 8 - it is not the port next to the uplink port, it is the uplink port.
-- End pre setup, if you have a hub/switch that is not part of a router.
#13 Disconnect your computer from behind the Netgear router.
#14 Setup a Static with these settings for that wired NIC.

For security precautions, unbind File and Print Sharing and the Client for Microsoft Networks from the second NIC.
#16 If you don't have at least two NICs, well..
For security precautions, unbind File and Print Sharing and the Client for Microsoft Networks from that NIC.
#17 Connect that wired NIC to any other port of the hub/switch but not the uplink port, port next to the uplink port OR the port in use by the Netgear's WAN/Intenet/ To Modem Port.
#18 Now Install the tool that is addressed in the first FAQ that I pointed you to in this post of mine.

Once installed, don't forget to use ** CTRL-ALT-F7 ** to reveal several "hidden" tabs, the signal levels and error counters, so forth.
#20 In the tool go to DSL tab.
#21 If your computer has two NICs, please post the info from there.
#22 If your computer only has one NIC:
a) Copy down the info from there.
b) Disconnect the computer from behind the hub/switch that is between the Westell modem and the Netgear router.
c) Connect the computer to one of the Netgear's LAN ports.
d) Change the NIC to use DHCP.
e) Then post the info that you got from there....
---- End directions if you have a hub/switch that is not part of a router.
If you don't have a hub/switch that is not part of a router, consider buying one. A cheapo 4-port hub/switch will do.

Unless Verizon can do something to shorten the loop or improve the quality of the line, I'm afraid you're stuck at 1.5Mbps 
. The line could probably handle 200kbps more to suit the full 1792kbps/448kbps rate, which delivers 188KB/s down, 48KB/s up but that's really all you'll get out of it. ADSL2+ won't help too much in this case.
