The replacement wireless access point for GS corridor west has now been installed. The signal may be variable over the next day or two whilst the system automatically calibrates the new hardware. After that, please report any wifi signal issues to service-desk@cl.cam.ac.uk.
We have also separately been planning a major upgrade to the wireless network in the building, expected to take place in a few months' time. That should improve the wifi signal and wireless network performance throughout the building.
