T-Mobile Wi-Fi CellSpot AC1900 Gigabit Router (Pre-Owned) Expired

Use code CPOROUT to bring it down to $39.99 + tax.


You can flash this router to an RT-AC68U: http://www.bayareatechpros.com/ac1900-to-ac68u/. There are few change/additions needed in the guide before the latest ASUS firmware can be flashed, though.

• Avoid CFE 1.0.2.5 from the RT-AC68P, as the newest Asus firmwares (3.0.0.4.384.20624 and later) detect this on the TM-AC1900 and revert the mod. Instead, use CFE 1.0.2.0 US AiMesh; it was dumped from an actual RT-AC68U by user goggles99 at SNB. The CFE generator [pipeline.sh] by danielfeng has this version available.
• Some TM-AC1900 ship with a firmware version that allows SSH access. If you get one of these, you can skip steps 5-10 of the guide. To check if you have SSH available, go to Administration > System in the router configuration interface. If your firmware permits SSH, there will be a setting to Enable SSH. If so, choose Yes, then Apply. Move on to step 11.
• The T-Mobile certificates have to be wiped from the mtd5 partition. This can be done after all of the steps in the guide have been completed, but must be done before any newer version of ASUS firmware is flashed. As of this writing, the firmware included in the bayareatechpros guide is 3.0.0.4.376.3626, so the steps below should be performed when this version is running on your router.

Wiping T-Mobile certificates from the mtd5 partition

These instructions originally existed on SNB before that forum thread was shut down [snbforums.com]. Credit to XVortex and rdallen. After you've performed these steps, you can flash 3.0.0.4.384.21045 (and possibly newer) using the GUI.

SNB now disallows discussion [snbforums.com] about converting TM-AC1900 to RT-AC68U with AiMesh. So, modding information may be a bit harder to come by going forward. Some discussion has moved to this thread [whirlpool.net.au] on whirlpool.

Other Tips:

If you are having problems accessing the mini-CFE webserver this works:

1. Power off the router using the power button
2. Set your PC's IP to 192.168.29.2 (assuming the recovery mode is gateway is 192.168.29.1)
3. Navigate to 192.168.29.1 using your browser -- the browser continue to try and access the page until it is available
4. Press and hold the reset button while powering-on the router
5. When the mini-CFE webpage appears on the browser, release the reset button
6. As long as the browser status is still spinning -- looking for a webpage -- the mini CFE web page will load

For those following BayAreaTechPro's flashing guide, here is a guide on the Internet connectivity during the process. This tells you when to connect/disconnect the PC from the Internet and connect to the router.

Assuming you are using a single PC to do the flashing:

• You are connected to the Internet via your old router in Steps 1-3.
• Then you are connected to the new router in Steps 4-14 (no Internet).
• Now you reconnect to your old router to get on the Internet. "Reset PC IP back to default" (as in Step 21) should be done here as Step 14a.
• You are on the Internet via your old router for Step 15. "Set static IP for PC" (as in Step 4) should be repeated here as Step 15a.
• Reconnect to the new router for Steps 16-24 (no Internet). From now on, your PC can stay connected to the new router.
• In Step 24, you can connect the new router to your Internet modem. After a normal configuration, your PC should connect to the Internet now via the new router.
• Flash your desired/updated/newest firmware to the router via a manual upload on the router's Firmware Update screen.

Having Trouble Getting a AiMesh Node to connect to your main AiMesh router (confirmed working on firmware 3.0.0.4.384.32799) then follow this tutorial from vboyz103 (Click me to go to his original post or read below)

For those who look to setup Aimesh, do:

1. Complete mesh setup of the Mesh Router (this is the "master")

2. To set up "slaves" or Nodes, first factory restore via Admin menu.

3. Once Node router rebooted, plug your laptop into LAN port (yellow ports) of the Node router.

4. log in and go thru setup wizard and select type to be AiMesh Nodes. Click next and you will get prompted to redirect PC message.

5. Now unplug the ethernet cable from your PC, setup PC to connect to the "master" via wireless that you setup in step 1.

6. Plug the ethernet cable into the back of the master router LAN ports. At this point the cable should be connecting your AiMesh Node router to the AiMesh Router (master) both via LAN ports (yellow)

7. At the main page (General Map) click AiMesh icon and look to the right. The portion of the page will refresh. You will see a search button click it. Within few secs, the Node router will appear and click Add.

8. Done.
--------------------------
After completing the above steps to convert your router to RT-AC68U using CFE 1.0.2.0 US AiMesh, you may notice the CFE defaults to clkfreq=800,666 and will revert to default after reboot if overclocked.
To make the overclock stick, follow these steps from the whirlpool forum:

To manually set the clkfreq the following SSH commands can be used which allow the clkfreq to survive a device reboot:

nvram set asuscfeclkfreq=1000,800 && nvram set asuscfecommit=1
nvram set clkfreq=1000,800
nvram commit && reboot

People have reported using the following clock speeds: 800,666, 1000/666, 1000/800, 1200/800, or 1400/800
--------------------------
In BATP's steps 17-19, the green text should appear in Putty after issuing the three commands.
--------------------------
Writing all FFs to the mtd5, the green text should appear in Putty after issuing the two commands.
