My laptop keeps saying default gateway not accessible even though it has all the routers information
Give a little more information. Such as what OS. Make and model so forth. This way someone can help you.
My laptop is a gateway with a 64 bit operating systemx64 based processor running windows 8.1 Intel(r) CPU firstname.lastname@example.org 2.20ghz
Try to disable the adapter with Device Manager and enable it afterward.
