Sorry I wasn’t able to reply to any posts. Thanks to moderator Johnex fixing the problem.
Here are screenshots of the hotel’s wifi environment:
Screeshots from Wifi Analyzer app on cellphone:
IHG Connect signals changed fast, every few seconds, jumping around on different channels and strengths, most of them are hidden:
After found all those info, I did these:
- Installed Termux from Google Playstore to my cellphone, for SSH client.
- Launched Termux, then installed SSH package.
- Connect to MT300N-V2 wifi.
- ssh root@192.168.8.1
- cd /etc/config
- vi wireless
- there’s already a section in the file “wireless”, I just updated the last section with hotel’s wifi info. Here’s a screenshot of the updated file:
The lines that were updated under section “config wifi-iface ‘sta’” are these five lines:
option ssid ‘IHG Connect’
option channel ‘6’
option bssid ‘EA:CB:BC:4A:5A:47’
option encryption ‘none’
option disabled ‘0’
From Wifi Analyzer’s results, pick up the strongest signal, use that MAC address to change bssid. Doesn’t matter if that signal is hidden or not, just use that. Also use its channel to update option channel. Encryption is none, since hotel has its own log in web page.
After the file is updated, run command “wifi reload”, or just reboot the router.
The router should be connected to ‘IHG Connect’ now.
I think I let router scan one more time, and see ‘IHG Connect’ showed up. Then let router connected to it. However, I run many scans afterwards, but never see the SSID anymore, from router’s repeater scanning page.
Open browser, try a web page, maybe “http://”, not “https://”. Will be redirected to hotel’s log in page. Fill in info, logged in for the first time. Afterwards, the router should automatically connect to hotel wifi every time powered up.
The first time, I used a MAC address of a weak signal, got very slow speed:
Then realized something, changed to the strongest signal’s MAC address:
Hope that could be useful to people who may get into the same situation.
