I have recently changed my home broadband provider, and since I have changed provider, the internet speed on my personal laptop has drastically slowed down. Initially this was because Norton 360 had identified the network as a public network, however, I have since changed the settings to update the network to a private network, however, this has made little to no difference.
I have a work laptop, which does not use Norton 360, and I get in the region of 70mbps download speed, in addition my smartphone also gets around 70mbp download speed, yet the laptop with Norton barely gets 10mbps download speed on a good day.
All 3 devices are sat side by side on the same desk and show full wifi signal, yet only the device with Norton installed is being impacted by slow download speeds.
