Can someone PLEASE help me fix my internet?

[Anthony]

Didn't get any help last time..

My laptop's connection to the internet isn't working while every other device is working fine. I did multiple tests on the cards, the router, and the laptop itself. Everything is positive.

However, when I wake it from sleep mode, I experience a few problems at random:

It takes more than a minute to connect.

"Unidentified network"

The router doesn't show up in the network sometimes, despite being connected

"Windows cannot connect to the network" (REALLY common)

And many more.

It's starting to piss me off. I tried everything I can to fix it, but these last few days, these problems have persisted. Please help.

Windows 7, Inspiron 1545 Dell

I dont care what windows you are using but no windows version of any kind is ever good enough to use in sleep mode! it damages the hard disk and increases fragmentation to the hard disk!

the best option when you are not using the computer is to turn it off not sleep mode to fill it in with more dust and lint and in no time to start wondering why its overheating so fast!

delete all the list of networks that you have set up in the previous time and all the WiFi spots and set it up to have only one all over again and try to connect again

So is your problem with sleep mode or your computer in general? If it does this after you awake it out of sleep mode, then stop using sleep mode is all I can suggest really.
EDIT: Basically what the guy above said.
