MikroTik hAP ac² - Mobile WiFi or phone tethering （备用宽频）

Mobile WiFi or phone tethering （备用宽频）

有的时候，因为要更换ISP，而新约有没有开始，那么这段内家里的电脑就没有网用，家里人一定会有怨言，那怎样办好？而反观现在很多data plan中都有无限上网，虽然速度流量超过某个G会降速，但是降下来的速度是依然可以用，现在分享一个可行方案就如下:

设备：
i. Mobile devices (mobile phone tethering or mobile WiFi (MiFi)
ii. 7日，14日，一个月无限上网plan（在鸭记有很多选择）
iii. MikroTik WiFi Router (hAP ac^2)

大家可以根据下面思路去configure MikroTik WiFi router

1. Backup你的旧的router configuration。

2. Reset你的router

/system reset-configuration skip-backup=yes

.

3. Remove the default wlan1 port from the default "bridge" bridge

/interface bridge port
remove [find interface="wlan1"]

複製代碼

.

4. Set the remote profile name "remote-ap" and password = "remote-ap-password" for the MikroTik WiFi router

/interface wireless security-profiles
add authentication-types=wpa2-psk mode=dynamic-keys name=remote-ap \
wpa2-pre-shared-key=remote-ap-password

複製代碼

.

5. Set the default password (="default_password") for the wlan2 (5GHz)

/interface wireless security-profiles set authentication-types=wpa2-psk mode=dynamic-keys wpa2-pre-shared-key=default_password [find name="default"]

複製代碼

.

6. Connect the remote AP with SSID = "mobile-phone-tethering-SSID" with the password profile = "remote-ap"

/interface wireless set wlan1 ssid=mobile-phone-tethering-SSID mode=station frequency=auto security-profile=remote-ap disabled=no

複製代碼

.

7. Set the wlan1 as a DHCP client

/ip dhcp-client add interface=wlan1 disabled=no

複製代碼

.

8. Set the NAT with masquerade

/ip firewall nat add action=masquerade chain=srcnat out-interface=wlan1

複製代碼

.

9. Reboot your router

/system reboot

複製代碼

Now you are able to connect the internet using the LAN port from 2-5 and 5GHz AP. You can add a virtual VAP1 of 2.4GHz and tie this VAP1 to the network bridge (name=bridge) in the WiFi router.
