IR305 from Verizon Slow Upload Speed/ Trouble Connecting some Applications

If you purchased an IR305 from Verizon and experiencing slow upload speed or having trouble connecting certain Apps, please change the following settings.

  1. Connect to IR305 using WiFi or ethernet cable
  2. open on your web browser
  3. login using adm/123456
  4. go to Network>>Cellular, check Show Advanced Options
  5. uncheck Static MTU
  6. click Apply at bottom

Since Verizon is using a different network structure than the other cellular providers, they are using a smaller MTU which is 1428. If we set MTU to 1500 in the router, then any upload from the router larger than 1428 would be dropped by Verizon network.
