Hello, your home connection is 100Mbps. On Ookla tests, using the LAN gives 80-90Mbps, while Wi-Fi via TP-Link DIR615 at 2.5GHz drops to 30-50Mbps. Your device doesn’t support 5GHz and only has 20MHz and 40MHz channels. Consider checking for interference, signal strength, or network congestion on the Wi-Fi side.
Identify the Wi-Fi standard your connection uses. Ensure it matches both your router and your card's capabilities. Consider distance, obstacles like walls, and nearby Wi-Fi signals on the same channel. The setup should handle up to 300 Mbps with Wi-Fi 4 (802.11n).
Which wireless card are you connecting? Around 100mbps might be achievable with this router.
I am regularly at about 5-7meters away from the Router - at that time, there is about a brick wall in between me and the router. But the tests I did was keeping the laptop right beside the router so as to get easy access to the LAN ports in the router. I believe all my neighbours are in the same 2.4Ghz band itself , don't know which channel though. Can we analyse it with any app? Or do we need to go knocking on them? I don't think there are any iot or smart home devices in my neighborhood. But there are about 3-4 wifi hotspots that we could theoretically get interference from. But not consistently though. As we have brick walls, most of the external interference are also very week. On my laptop, where I ran the tests, it uses a Wifi6 compatible card. So I do not think the issue is with that. Also we get the same speeds on testing with other mobile devices from home too. So I have narrowed it down to the router.
There are tools available for this task. You can also retrieve a list using the command line with netsh wlan show all. Click the Wi-Fi icon in your taskbar, wait for the list to load, and then you’ll see neighboring networks and their channels. Your router may already provide this information. It displays channel congestion levels, helping you choose the least busy one. It outperforms my laptop in this regard. You can also view your own channel and connection speed directly from Windows: https://www.makeuseof.com/windows-check-...ter-speed/ The router supports Wi-Fi 1, 3, and 4. The issue is which card standards it recognizes—such as 1, 3, or 6. In that scenario, the most common supported standard would be Wi-Fi 3, limiting speeds to 54 Mbps. Alternatively, if it only works in the 5 GHz band, you’d get faster speeds there. I recommend checking the mode described in the link I shared earlier.
2.4 Ghz appears in many everyday devices beyond WiFi. The microwave you own uses it to heat food, cordless phones, Bluetooth, wireless keyboards, and mice work on it too. I’ve noticed that water pipes inside walls can interfere, and weather changes sometimes disrupt my signal. From what I understand, 2.4 and 5 Ghz are generally open bands as long as they comply with regulations.
Hello, I understand this has been a while since anyone was discussing it. I reviewed some notes while considering buying a new router and shared them here via a GitHub link. Could you confirm if my observations are accurate? It would also be useful for others joining this conversation later.
Channels have limitations depending on the region. In the US, channels 1 through 11 are the only ones permitted. With 5 GHz, some frequencies overlap with radar systems, meaning DFS channels aren’t universally available. Not all routers support DFS because it needs special government approval, especially in the US.
Thanks for the details. I'll review them and include them later.
