I wish the T-Mobile Home Internet Gateway was JUST a modem!!!

It's been two years, and the brand-new Fast_5688W gateways are still locked down.

I'm still in the try-before-you-buy period — but unless I can find a workaround to disable NAT and DHCP, I may bail and tell them that provisioning with such a dumbed-down device is a deal-breaker.

Here is a PowerShell script for disabling WiFi on the 5688W, in case it's helpful.

$ErrorActionPreference = 'SilentlyContinue' #disables error reporting function token { $Pass = Read-Host "Enter Password For The Gateway" #admin passphrase for the gateway, not WiFi $body = @" { "username": "admin", "password": "$Pass" } "@ $login = Invoke-RestMethod -Method POST -Uri "http://192.168.12.1/TMI/v1/auth/login" -Body $body $token = $login.auth.token $global:header = @{Authorization="Bearer $token"} } function Show-Menu { param ( [string]$Title = 'My Menu' ) Clear-Host Write-Host "Options for Gateway" Write-Host "1: Press '1' to Turn Off 2.4G Wifi."
