have you tried another computer on that router ? 54 mbps is the connection speed between your laptop and your router. Your laptop recognized your router and the two are connected.
Try another PC/Laptop on that router and if it doesn't work, then check your router settings (you may need to redefine your username/password if you have broadband or DSL)
Otherwise you can already access your router settings from your laptop. Although I don't know what router you have but for the D-Link that I had, I used to write in the address bar : 192.168.0.1
I'm having problems with my laptop. It is a Dell Inspiron 1546 with Windows 7 Home premium, AMD processor. When I start up google chrome, it doesn't load up, I leave it sitting for 15+ minutes and it never goes to the homepage(google). I've checked with the network and sharing center and it says the speed is 54mbps. We recently switched our router to an SMCWBR14S-N4 because our other one died. The wired connections work just fine. I've already scanned my laptop with malware bytes, avast, and ad-aware. I'm lost right now and am not sure wether it is my router or my laptop. Please respond, I'm feeling desperate.
