Here are some tips to improve your wi-fi experience:
Use the latest wireless driver software
Install the latest version of wireless driver software available for your device and keep it up to date to take advantage of fixes and new features that can improve the stability of your wireless connection.
Take advantage of 802.11ac / 802.11n
If your wireless device already supports 802.11ac or 802.11n, change your eduroam configuration from WPA/TKIP to WPA2-enterprise/AES to connect in 802.11ac / 802.11n mode. You can refer to the corresponding configuration guide to make the changes. If you are using an older notebook that only supports 802.11a/g, you can consider buying a 802.11ac / 802.11n USB adapter to enjoy the benefits associated with 802.11ac / 802.11n.
Enjoy less interference
The 5GHz frequency band (802.11a/n/ac) is less noisy and has more wireless channel available for use than 2.4GHz (802.11g/n). If your wireless device is capable of supporting 802.11a, make sure you have enabled it. If your wireless device supports 802.11n or 802.11ac, you can enable a feature called channel bonding to help increase the connection speed in the 5GHz band. Channel bonding is not available in the 2.4GHz band due to channel overcrowding.
Remove wireless broadband routers
These routers will interfere with other users. Please disable the wireless connection in your broadband router.
Turn off bluetooth devices when using wireless
Devices, such as a bluetooth mouse, bluetooth USB adaptor, and bluetooth headset, run in the same 2.4GHz band as 802.11g/n. If you experience a slow connection, shut down nearby bluetooth devices to see if it helps.
Minimize obstacles/clear the path
Some materials absorb more radio frequency than others. If you experience poor reception, move your notebook to try to uncover potential radio frequency absorbers/blockers.
