How can I extend the range of my WESTELL 7500? Please help.

I installed a security camera outsite of my house and unfortunately the modem/router is on the opposite end. The camera would connect on and off as opposed to on all the time when it was mounted inside.

I am researching around and it looks like I can get an extender? Are there certain ones to look for in terms of compatibility issues?

Or can I upgrade the modem/router? The Westell 7500 was provided by Verizon at start of service.

Thanks in advance.

If you want a wireless extender, it must support 802.11b and 802.11g.
