My uncle just gave me a router to go along with my new laptop: HP: AMD Turion™ II. We use Suddenlink cable internet. The router worked quite well with the modem, my new laptop, and the desktop until my uncle suggested encrypting the router on my laptop. He changed the passkey and set it to "TKIP". I lost the connection immediately after. I tried using the new password he wrote down but it did not work. I also tried setting it back to AES and changing the passkey. It failed.
The desktop still had internet connection, but the laptop did not. I used the reset button on the router as well as System Restore and a reboot and nothing helped. I then tried to rename the passkey again, tried to change it back to AES, and unplugged both the modem and the router, resetting them both and then plugging them back up. This resulted in my desktop losing connectivity, so I had to disconnect the router and hook the ethernet cord directly back into the modem to regain internet for the desktop.
I have no clue what I'm doing. Apparently, neither did my uncle. No one else around me seems to know either and Linksys support leaves much to be desired.
I would really like to change it back to default but am unsure how. Will I have to replace the router? Or worse, the laptop?
I appreciate any help I may receive in making my home wireless again.
