One laptop in house won't hook up to new modem
We recently purchased a new modem/router combination and all the phones, tablets will hook up wirelessly to the new modem/router. One computer will not hook up wirelessly. I have tried many fixes, but nothing works.
This laptop was working just fine with the old modem, but we were finding the download speeds slow, and we had received a letter from Comcast saying they recommend we upgrade to a DocSis 3.0 from our current modem. It is faster and we stream better, but I can no longer hook up this computer. (The exact same issue happpened in our home up north when I bought a newer modem/router and I couldn't resolve it - I took it to the computer store and he hooked up right away and of course, I felt very stupid...... also while travelling I hooked up to my son's internet no problem)
I am suspecting it might have something to do with the router/modem combination?
Any thoughts or suggestions?
Thank you in advance.
