Wifi speed at half strength varies based on your device and network conditions.
Hello everyone, I've been facing this problem for some time and haven't managed to resolve it through my own checks. My setup includes a DSL connection with about 75 Mbps down and 15 Mbps up, using an ASUS AC3100 router as my home access point. The issue is that while the 2.4 GHz band can reach up to 54 Mbps, I'm not seeing the expected performance. On my 2.4 GHz network, the speeds are only around 35 Mbps, which is roughly half of what I should be getting. Even after eliminating interference and other factors, the speeds remain unchanged. What could be causing this? How can I fix it? Thank you!
802.11a supports speeds from 6 to 48 Mbps, 802.11b offers 1 to 11 Mbps, 802.11g provides 6 to 54 Mbps, 802.11n reaches up to 600 Mbps, 802.11ac can hit 1734 Mbps with 1024QAM at 2.4GHz, and 802.11ac at 5GHz goes up to 2167 Mbps. The 2.4GHz band typically handles lower-priority devices, while 5GHz is reserved for essential equipment and Ethernet is suitable for any device that supports it.
DSL, right? How do the speed checks compare when you're plugged straight into the modem versus the router?
Initially, 2.4Ghz operates only with 802.11n, even on 802.11ac devices since they prioritize 5Ghz for WiFi 5. Expect roughly 72 or 144Mbit speeds because most setups use just 2x2 MIMO and a 20Mhz channel width unless you're in a remote area. Real performance usually falls short compared to 5Ghz due to interference from nearby networks. I've observed drops as low as 20Mbit, though it has improved slightly as nearby devices adopted 5Ghz. Currently, my test averaged 60Mbit, with fluctuations between 40-83Mbit. By contrast, 5Ghz AC can achieve up to 600Mbit thanks to wider channels. 2.4Ghz might work again with 802.11ax/WiFi 6, but I haven't tested it in practical situations.
I used to experience quicker connections with wireless G. It wasn’t a huge jump, but still better than standard. The original poster should be able to achieve even higher speeds. Proper gear is essential, as most clients lack the right equipment, since companies often use low-quality adapters. Despite this, wireless N can reach 600 Mbps even with the 2.4 GHz band and new methods. The OP might be able to surpass 100 Mbps. I’ve definitely seen over 100 Mbps on my old wireless N router back then.
For a long time I relied on my IoT gadgets on G due to their superior reliability. In theory, N could achieve 600Mbit using 4x4 MIMO and a 40Mhz channel width. However, in real-world conditions, this performance rarely materializes even with the right hardware. In a clean setting it might reach 100Mbit on a 2x2 MIMO with a 20Mhz channel, but comparing it to the past is difficult because WiFi interference has increased significantly. Additionally, more Bluetooth devices are now in use, adding further disruption.
Run a wireless survey with WiFi Analyzer. Share the 2.4GHz scan results from the 'Analyze' section, highlighting your SSID. Also provide your router's WiFi configuration details.
