I have found that when IPv6 is enabled on the Mac is doesn't always play well. So @CaptainE if you would like to turn this off you can do so using the following.
sudo networksetup -listallnetworkservices
Password:
An asterisk (*) denotes that a network service is disabled.
Ethernet
Љ 2
Љ
MT65xx Preloader 2
MT65xx Preloader
USB ACM
MT65xx Preloader 3
USB Controls
MT65xx Preloader 4
Display Ethernet
LAN-2
iPad USB
Display FireWire
Wi-Fi
Bluetooth PAN
Thunderbolt Bridge
Mook@iMac ~ %
From the list select the network(s) you want (in my case, Ethernet and WiFi) then use:
sudo networksetup -setv6off Ethernet
sudo networksetup -setv6off WiFi
If you want to re-enable these at any time use
sudo networksetup -setv6automatic Ethernet
sudo networksetup -setv6automatic WiFi
You will need admin rights to do any of this.

Thanks for your posts @CaptainE and apologies for the delayed staff response. I'd firstly second dvorak's initial response at splitting the 2.4GHz and 5GHz wireless frequencies as these appear to be merged together into a single network name although I'm unsure if you've historically made the change, tested things and then reverted back.
I'd also second Mook's suggestion at switching IPv6 off as this feature on older Mac's tend to not play well with some routers, although that's most commonly on OS X Snow Leopard or earlier and our Hub Zero routers. An easier way to do this without going into the Terminal would be follow the below steps:
- Go to System Preferences from the dock bar at the bottom of your screen
- Click on Network
- Select Ethernet and click on Advanced
- Click on the TCP/IP tab
- From the drop-down menu on Configure IPv6, change this to Off
- Click on the OK button and acknowledge any prompts you get to save the changes
- Repeat the above steps selecting Wi-Fi at step 3 rather than Ethernet
For good measure, I've tested your line and the tests are showing everything's OK with the line itself.
Let us know how you get on.
