It's: Dell Wireless 1707 802.11b|g|n (2.4GHZ) what can I buy to improve the situation? 1. If you can plug in via Ethernet, that will be much faster. 2. Your WiFi card uses a Qualcomm chipset, limited to maximum 150 mbps on  802.11n (slower on b and g), though you're unlikely to see that in real-world performance. 3. Your card is 2.4 GHz only. That is a crowded spectrum and subject to much interference. If you have other WiFi signals nearby, such as neighbours, then your performance will degrade significantly. If you are in a highrise building with many neighbours close by with other WiFi networks, then you may be getting the maximum speed that you're likely to achieve. I saw the same when I worked on a friend's Inspiron, with 2.4 GHz only, in my building. 4. If you want, you could buy a dual band WiFi card that supports 2.4 GHz and 5 GHz. Switching to 5 GHz, if your router supports it, would achieve better performance in a crowded WiFi environment. You could even go for a card that supports WiFi 6, again if your router supports that. 5. An alternative to replacing the card is to buy a small external WiFi receiver that connects via USB port. There are many available.
Hello everybody! I have internet fiber at home but I'm wondering if my latitude 3550's wifi can go with it. I think it can't because my speed test says I'm going at 70Mb/s in Wifi (my smartphone 300Mb/s). Is there anythink I can buy to improve my DELL' speed test? Thank you
