I have a TP-Link router with an EE sim. My work laptop has recently had Zscaler installed. The speed on the laptop has decreased dramatically. IT tell me the speed with zscaler is not relative yet I can get between 40-100mbps on other devices connected to the router but barely 1mbps on the work laptop!!! They say it must be the ISP. Is there a conflict with EE sim and zscaler?
