The pings to google are very consistent and it does look like a wireless problem. For the distance and obstructions, I'm literally like 10 feet away from the router but there is a wall between my computer and the router. Using a cable is a viable option but I would just have to move the modem to a better location. And the router does have a 5GHz band. How would I connect to the 5GHz band with an ethernet cable? It only shows that I'm connected to the 2.4 GHz on Windows.
10 feet should be fine, even through a wall. Are we talking a normal dry-wall? No special metal coated insulation in the wall or anything like that?
If you can use a cable without significant inconvenience then it's always the best way. While wifi tech is getting better and better, there is just no substitute for a dedicated piece of copper which is (in a normal residential environment) totally immune to interference, congestion, etc. Usually, you plug it in and it just works for ever and ever.
If you'd prefer to stick with wireless, the 5Ghz is a wireless band is definitely the best choice for a 10ft 1 wall connection (assuming a standard dry wall). You just connect to it using your wireless adapter (not an ethernet cable). "Dual band" routers broadcast two separate wifi networks, with their own SSIDs (that's the name that you see when you look at the available wifi networks). One will be on the 2.4Ghz band and one on the 5Ghz. The 5Ghz band has far more available channels which means in a densely populated area, there's much less chance of congestion.
If you can get into your Router via the web based admin, look at the two wifi networks and figure out what your 5Ghz band is called.
Then go to your PC and see if you can find it in the available wifi networks. Some very cheap or old wireless adapters will only support the 2.4Ghz band, in which case when you browse the available wifi networks in your area, you'll only see the 2.4Ghz network as an option. If that's the case you're probably best served reverting a cable (best option anyway!) or upgrading to a better wifi adapter with dual band support. Once you can find and connect to the 5Ghz network, run your pings again and see what it's like. Just bear in the mind that congestion only happens when people around are actively using their wifi. So if all your neighbours work 9-5 jobs, testing at 1pm on a week day is NOT a good way to see whether your wifi is going to be reliable.
