The adapter won’t deliver high speeds over WiFi; Intel states the maximum is 300Mbit for WiFi 4/n, which translates to about 50-75% of that in practical use near the router. Depending on your laptop model, a newer WiFi 5 card might work better. USB adapters are available but aren't ideal—they require large devices and can be fragile when handling a laptop. Smaller options struggle with signal strength.
Issues with WiFi include inconsistent speeds and interference from various factors. My top performance on WiFi 6 is around 1.44Gbit, yet it's not reliable for everyday use. I've noticed my phone achieving 800Mbit in the same spot, but it's currently only reaching 500Mbit. The challenge becomes more noticeable with older WiFi standards.
It seems the conditions affecting performance are unpredictable and often outside our control. There’s no certainty about why speeds drop or improve. Even after updating all equipment, the issue persists. I’ve experienced fluctuations from 900Mbit to 500Mbit without any clear cause. The challenge is maintaining adequate speed on the airwaves, which are shared. A minimum speed isn’t guaranteed. If possible, ensure your WiFi operates faster than your broadband, so it maintains full capacity during drops. For now, changing channels might help, but it’s not always feasible.
