Router Connection Issues

For quite some time now my computer has been experiencing severe issues that keep me for connecting to the internet. What usually happens is a sudden drop in internet connection a few seconds after connection, from which it recovers saying "internet connection" but I still get stuck in resolving host.I know very little about networking and because of this I have not tried many solutions. First of all whenever this occurs I am completely unable to access webpages but I can still get to internet based programs such as Skype and games connecting to servers. Also I have tried connecting with a wired and wifi connection, as well as connecting both at the same time, and cannot access the internet through any. All the Apple computers in the house connect fine. When I connect my computer to the internet through my Iphone's hotspot I have no problem connecting but it seems as if the resolving host stage is much slower but this may very well just be my imagination. Before I posted this a day after I wrote this I came home and attempted to connect through my Iphone but was unable along with being unable to connect to an extender I can usually connect to. I have run a full scan with both ESET antivirus and Malwarebytes which have both found nothing. Any feedback would help.
P.S. I have a Ubee router
Thanks in advance!
