Before u bought anything pls google and check the hardware revision don't assumed everything is good as it's brand :-)

Example Linksys WRT54G they are so many versions of it and the most fakap version is ver 7. Due to so many popular mod for the router they decided to change the hardware inside it in newer version and until now only GL can support 3rd party firmware. Most new release have RAM limitations and fakap features.

For the modem i don't prefer all in one. I have been using AM300 for almost 7 years running 24/7 and no issues at all with my 1.5 Mbps and now 4 Mbps .
