My wireless problems with new firmware are finally fixed:
After upgrading to 3.0.0.4.384.10007 and still having trouble i did the following:
- Saved all router-settings for security (backup)
- Wiped NVRAM (Full factory reset)
(Updated HowTo from a user here)
"Telnet to your router"
1. Say if its using 192.168.1.1 for its address
2. Enable Telnet in router settings (administration -> system) and save
3. Enable Telnet client service in Windows (Apps & Features -> Programs and features -> Activate or deactivate Windows features -> select Telnet client checkbox - OK)
4. Go to start/run type "cmd" press enter
5. Type "Telnet 192.168.1.1" press enter
6. The login is "root" (if possible) or your "username" the password is whatever you set the password for the router.
7*. After login type mtd-erase2 nvram
8. Now type reboot
9. Wait about 4 minutes, the SSIDs for 2.4GHz and 5GHz will appear (ASUS_xyG).
(*ARM-based routers might use mtd-erase -d nvram instead of mtd-erase2 nvram)
- Setup RT-AC88U with Setup wizard
1. Connected to the Asus_2.4G wireless network, the browser took me to Setup-Wizard
2. Followed the steps with the wizard (ISP, new username + password), didn't select any checkboxes for seperate SSIDs at Wifi-settings (only WPA2-Security and one SSID for both networks)
I restored no settings-backup.
After the setup i changed nothing in the Asus settings menu, except disable "Airtime fairness" for 2.4 and 5GHz in Asus' Wireless-Professional tab, to have stable Audio-Streamingdevice detection (Chromecasts, Sonos,..).
I noticed Smart Connect is enabled by default, and i changed not a single Smart Connect rule setting. Fortunately it works out of the box!
3. Manually assigned IPs for my audio streaming clients and NAS in LAN-Settings (DHCP server).
4. Unplugged Asus router & modem for 10 seconds, rebooted PCs, smartphones and all other devices. Had to reset my Wifi settings on my printer to reconnect, don't know why, but worked.
- Router works without any problem
1. Speedtest constantly maxed at 75Mbit/sec up & down (= maximum speed) ✓
2. Youtube and other video streaming services work, no connection drop or quality drift to 144p ✓
3. My Audio streaming devices are detected instantly, and play music without problems ✓
4. RAM at 113MB and CPU at 4% ✓
5. Hardware acceleration enabled by default and seems to work ✓
5. Clients list shows all active devices without interupts ✓
6. Smart Connect works out of the box ✓
7. Haven't activated AiProtection yet, i'm afraid it might be the one last thing to mess my router up again. ×
Hope it helps others,
