2. Right-click "Command Prompt" in the search results and select "Run as Administrator"
3. In the command prompt screen, type: ipconfig /all

You should be seeing something similar to this below. (I censored out my own info, but you should get the picture.)



The only parts we care about right now are the dates/times listed for "Lease Optained" and "Lease Expires". I suspect that when you check, they will be set for exactly 30min apart. If this is true, then unless you are comfortable with the idea of mucking about in your router's firmware, you will probably need to contact your ISP and have them increase the lease duration to at least 24hrs. Please let me know the results of your tests. ^^

(In my case, I have it set to the maximum that my router will allow, which is over 3 months, but the maximum number of devices on my network is always the same 3 devices. If you have tons of devices connecting to your network, don't set it anywhere near this high.)
So I tried the ipconfig/all command.. my results were: Lease Obtained..... Saturday, November 17, 2018 4:40:40pm
Lease Expires...... Monday, November 26, 2018 11:23:38pm
