Just to let you know I’m no pro at this. A lot of trial and error -
hence my “lab”. Plus, I ended up having to return my Trendnet as it died
a few weeks later. However, a defective router doesn’t sound like your
problem. Make sure that the network cable going from the Netgear to the
Trendnet ISN’T connected to the latter’s WAN port. It should connect to
one of the – usually – four LAN ports.

Alternatively, you can try the following. Before doing this you may even
want to uninstall any software that came with the Trendnet. 99% of the
time, this kind of software is unnecessary crapware. Most consumer grade
routers can be configured using a web browser. I also make a few other
assumptions in the following, but hopefully I’m right about them

First, disconnect your Trendnet and boot up one of your PCs. Make sure
that it’s connected to your router and that the modem is on.
Click on Start -> Run -> type “cmd’ then hit enter. ( “Win key + r” )
Type “ipconfig /all” then enter.
The line that says “Default Gateway” shows the IP address of your
router. Make a note of it. Example, 192.168.2.1
Also, make a note of the “DNS Servers”.

Second, disconnect the ethernet cable from the router to your PC and
connect it to one of the Trendnet’s LAN ports. ( PC < -> Trendnet ) Turn
on the Trendnet wireless router.
Check the instruction guide about accessing the web interface.
Typically, you’ll start up your web browser -> enter the Trendnet’s IP
address -> you may be prompted for a login and password (use the one in
the guide). Once you’re in, then you can finally start getting your
hands dirty.

Third, settings you need to change:

router IP address
-> if your Netgear is doing DHCP, make sure the address is outside the
DHCP range. For example, mine defaults to 192.168.2.10 to 192.168.2.100.
So, an IP address higher than 192.168.2.100 – like 192.168.2.250 – is safe.
Also, you’ll probably want it in the same group. So, if the default
gateway address (see above) was 192.168.0.1 (note the .0.1), then make
it 192.168.0.250

default gateway IP address
-> the same as your PC’s (see above). So the address of your Netgear router.

name server aka DNS Servers
-> the same as your PC’s (see above).

*Turn off / disable DHCP. You may also want kill the UPnP – a matter of
preference

*whatever you want re: wireless settings.

Fourth, turn off the Trendnet. Get another network cable to connect the
Trendnet (again use a LAN port) to the Netgear. In other words,
PC< ->Trendnet< ->Netgear< ->Modem

Fifth, the judgement day (tests).
1. Turn on the Trendnet and see if it lights up.
2. From your PC, start up your browser and try getting to the web
interface again – of course, you’ll be using the new IP address you set
for it.
3. From your PC, start -> run -> “cmd” again. Type “ping [Trendnet IP
address]“. You should not get the loathed “Request timed out” message.
4. From your PC again, “ping” the IP address of the Netgear router.
5. From your PC again, “ping google.com”

The first three tests are like general hardware tests. Like, I hope it’s
not busted.
The fourth one tests if your LAN (local area network) is okay.
The fifth one tests if your WAN (wide area network, for you aka
Internet) is okay.
If all is well, then you can progress to the laptop wireless stuff. Do
the ping tests and try web interface again.

If the thing fails the first three tests, I feel pretty comfortable
saying it’s time to take it back. Unless if someone else out there knows
more about this.

Hope this helps and GOOD LUCK!
