So, we had a couple of network/internet outages last week, and since they've been repaired, pages/sites are taking a few more seconds than normal to resolve (once located, they load at their normal rate). I'm thinking something has changed on my ISP's end. The DNS server IPs I have in network prefs are:

4.2.2.3, 204.117.214.10

The DNS server on my router is: 207.69.188.186 which I don't see a setting option to change that.

Any recommendations for others that may be faster?

If you trust/like Google you could try their free service.

Not endorsing it, as I have never tried it myself.

You power cycled the modem and router and restarted the computers?

You have a D-Link router right? Setup/Internet, at the bottom;

Primary DNS Address :
Secondary DNS Address :

I use Google's, partly because they are easy to remember 8.8.8.8, 8.8.4.4, but they seem to work well. My ISP's DNS servers suck, they don't automatically put the .com in for example, instead they take you to a search results page of theirs so you can give them a click, and the .com site I was going to sometimes isn't even listed till farther down rather than the first choice or so.

Remove the 4.2.2.3, 204.117.214.10 addresses from your network prefs, let the router handle DNS.

That seems to have perked things up a bit. Wait time for MacTech to respond is less now.
