Let me start with, I am non technical, I know nothing about computers. I use my laptop to run embroidery software which uses a lot of processor and excel/word etc.
I've just purchased this laptop and it's incredibly slow connecting to my Wi-Fi network, my old 6 year old laptop was incredibly fast. It took hours to download Google Chrome for example and just opening a browser window, takes forever to load the front page.
I have a NowTV broadband router (super fibre) and a Joowin Wi-Fi repeater. I've worked out that it's when I'm using the repeater that the Wi-Fi is slow, when I move near to the router it's quite a bit better, but still not as fast as my other devices. I work from a sunroom which is the opposite end of my house, so I use the repeater to boost my signal. My other devices can pick up a weak signal from the router, but this new predator doesn't even register a weak signal from the router. I also noted that it's on 5GHz when connected with the router and 2.4GHz when connecting to the repeater. The repeater only has 2.4GHz.
I'm happy to buy a dual band repeater, but I'm not sure if this will solve the problem. All my other laptops and televisions work fine off the Joowin repeater, so I'm quite perplexed why this new laptop doesn't when it cost so much! I'd expect it be even faster on my network.
Any ideas please? Thank you.
