Hi, I have a wrt54g v5, and it already has the 1.00.6 firmware on it. But the router always gives me a blank page after i've logged in, every few weeks, and i have to reset it to get the page to show properly, loosing all my settings at the same time. So i downloaded firmware 1.00.9. but when i choose to upgrade, it tells me firmware image invalid. the 1.00.6 firmware is 1.39MB, and the 1.00.9 is 1.37MB. what could be the problem? thanks in advance.
