Laptop can't connect to internet (nut can connect to wireless) when far from modem. How can I fix this?

I have a lenovo ideapad z570 with intel Wi-Fi link 100 bgn wireless adapter. The problem just started now, and I'm the only one experiencing this problem in my network.

When I'm close to the modem (within 5 meters) my laptop connects without any problems. But when I move farther, I lose Internet connection, but I still stay connected to the wireless network.

My driver is up to date, and I have the same adapter settings with a connected laptop.

I'm clueless, please help!

p.s. Do not suggest things like restarting my laptop or the modem, I already tried all that.

Seems like your windows update has some how corrupted your wireless card drivers. Go to device manager and remove your wireless card from the list and then restart your computer. The windows 8 shell auto discover your wireless card and install appropriate driver for your wireless card. Your laptop must have come with a Drivers CD if not go to manufacturers website and download Wireless adapter driver and save them on your D drive before you remove your wireless card from your device manager.

Your laptop has problems picking up the Wi-Fi signal i recommend you pick up a decent quality Wi-Fi dongle to replace your laptops Wi-Fi adapter.
