Here's one way to setup your RB951ui as a CPE.
951ui-2hnd to CPE with wired access on ports 1-5 (based on rOS v6.42.1)
USE Winbox.exe
1. Reset configuration to factory defaults
2.无线/高级模式
a. mode=station
b. SSID=hotspot network name
c. frequency mode=regulatory domain
d. country="your country"
e. amtenna gain=2
f. Click "Apply" and then "OK"
3. Bridge/Ports
a. Delete "wlan1"
b. Add ether1 to bridge
4. IP/DHCP Client change to Interface=wlan1
5. Interface/Interface List - Change WAN Interface to "wlan1"
6. System/Users - Change login Name and add login password
I thought about this, then I realized I only get 60 KB/sec anyway, so I decided just to leave the RB alone till I can get a real ISP, or maybe check on a different mobile network next month than Verizon.
