It sounds like the wifi cards in your refurb Dell laptops are bad. Or they have old drivers that are causing issues. Be sure to install the most up-to-date drivers from support.dell.com.

After a lot of trial and error, I noticed that the Wifi driver had updated as part of the Windows update. I rolled it back to the previous version, and all was well! So, the newest driver was actually causing the issue.
So, it's worth trying newer and older drivers.
I did update the drivers (by getting on another WiFi network - which gave me great speed). Once drivers updated, problem still persisted on my network. So, I don't think its the Wifi in the laptops as they worked fine on another network.
Verizon is sending me a new router I assume its another Verizon MI424WR Wonder if that'll help?
