i have a dlink router DIR-601..when i first used it it worked well net speed was fast even if i use it for wifi..then one day i noticed my net speed became slow..so i tried directly connecting my modem to my pc..speed came back to normal i used the router again it slowed down..back then it was ok even if 3 devices used the wifi but now even 1 greatly slows it down..i just checked my networked connection and the internal gateway and it says i only recieve 10mbps of the 100mbps..i cant even play well, loading 1 page takes forever
...is there anyway to prioritize the internet speed to my computer?i didnt change any settings it just happened suddenly...in order to play well its either i dont use the router or wait for them to stop using the wifi
