My Experience Setting Up FLOW’s TG2492LG-FLO WIFI Modem

I had one of the early purely modem devices for about 7 or more years now. I connected this to my Linksys router and I was set. The router is old and does not have all the features of modern routers but it worked. Did a house call the other day and saw that the person had the WIFI modem with their AVS setup. Then it occurred to me that I should switch out my modem for a WIFI modem. That way I wouldn’t have to worry about buying a new router when it was time for that. Made some notes after setting up my device and I am sharing it on my blog here.

  • I access the settings using the https link so that credentials entered are encrypted while communicating with the router – https://192.168.0.1/
  • I was told to skip the change password on first login prompt. Do it afterwards from the admin menu.
  • I chose to not broadcast SSID. You will have to manually add your WIFI to your devices if you do this. This is an extra layer of security.
  • I disabled 2.4 GHz. Reading that 5GHz gives less range but supports higher speeds and has less interference.
  • Love that there is a guest network separate for visitors where I can set a timer.
  • Discovered that there is nowhere to specify custom DNS. I can do that at the device level in Windows 10 for example if I really need it.
  • What I will do with the old router? Probably use it for experimenting with various custom firmware like DD-WRT, OpenWRT, and Tomato – if they support my aging router. Read that MAYBE you can brick your device or not go back to stock with custom firmware sometimes.
  • WIFI modem is behind Flow’s NAT. I guess if you need a public facing IP on the router you have to contact Flow.
  • There is a modem mode if you want your own connected router to be internet facing.
  • I always enable MAC address filtering to only allow my devices.
  • The branded settings UI is easy to use and simple and beautiful.
  • Initial passwords for the router settings and WIFI are labelled on the device. It is recommended that you change these.
  • Couldn’t find a user guide online. Arris does not have one and says I need to contact the ISP. Maybe they should put a link to one or something. Hire me to do a video guide.
  • You can restrict internet at certain times for certain devices. Maybe something for the kids.
  • I disable UPnP because I don’t use it and it feels more secure that way.
