My laptop has really slow internet while my other devices run around 100 mbps so i know for a fact it isnt a problem with my router or modem. My phone has has 121 mbps while my laptop can barely hold up at 5 mbps. I have a lenovo z40 laptop and xfinity internet with a netgear router. This REALLY complicates my work so PLZZZ HALPP!!! (my upload speed is somehow higher than my download speed so idk)
