Sometimes my laptop cant get the signal from my wifi (which is in the next room)ive had the same wifi setup for 7 years and was wondering if there is a time i will need to replace it , what is the time the system should last. This seems to be happening more often now, im running windows Vista on a 5 year old machine. I do always eventually get to log in tho as i say its happening more and more and taking longer to catch the signal.
My initial guess then would be the router, although my desktop used to have similar problems with connecting by wifi and ethernet. All I can suggest without wasting your money is to try and determine which end the problem is on by connecting to a different wifi from the computer or to your internet using another device.
