Laptop wifi slow, very fast at work, other devices are fast at home
Ever since upgrading to Windows 10, my Lenovo laptop has experienced paralyzingly-slow home WiFi performance. To test if it was my ISP or laptop, I looked at my wife's laptop in a performance test at the same distance away from my router, with all other home devices on airplane mode. Note: We use AT&T Uverse as our ISP.
- Wife PC (Chrome) - 17 Mbps
- Wife PC (Firefox) - 15.2 Mbps
- My PC (Firefox) - 7.2 Mbps
- My PC (Chrome) - 3 Mbps
At work, the same speed test (Ookla) run from the same server as my home tests (Duke University) showed 180 Mbps. I'll go through, from my rather inexperienced perspective, various settings I would imagine might be relevant to diagnosing.
