![]() If you use the default software, it’s very unlikely that you may cause any damage to the access point even if you set the transmit power to the maximum allowed value. Can a high transmit power damage the hardware? EnGenius ECW230S teardown. Perhaps an additional access point would do the trick or a mesh system – even a WiFi extender can fix this issue a bit better. I know what you’re going to say: hey, but I need to connect that device to the AP! And I get it, but pushing the transmit power to the maximum is not really that great of a solution. That’s because they need more time to finish a task due to the low transmission rate and which are going to be these slow client devices? Yes, it’s the farthest clients and the legacy devices. Fast client devices do their job immediately and don’t have much of an effect over the network performance, but slow client devices will hog the channel. What I mean by that is you need to take into consideration just how much time is allocated for each device in a certain channel. But there is more since even if it does successfully connect to the AP, you need to add the airtime into the equation. I already mentioned the possibility that the client device (smartphone, tablet, IP camera) won’t be seen by the AP, while the AP signal broadcast does reach this client. I know that this is what most of you are trying to achieve when you’re increasing the transmit power, but be aware that it’s not always a good idea to connect far-away devices to your access point. Most likely, half of your IoT devices won’t be able to connect to your network, you may experience co-channel interference and your neighbors will hate you. So, what happens if you push the transmit power to the maximum in the current conditions. That was about 300 feet away with multiple walls in the way, so yes, it is a performance that a lot of us dream of nowadays. Example of old hardware – Linksys WRT3200acm. This person pushed the TX to the maximum on the 2.4GHz band (the only available) and the signal would cross through multiple thick walls, through another building, reaching a laptop that could connect to this network. About ten years ago, someone told me that the newer ‘AC routers’ (that supported 802.11ac) aren’t reliable because they don’t reach very far, while a cheap B-Link router (some Chinese knock-off brand) was absolutely phenomenal. This way, your client devices will see the access point from very far away.īut that doesn’t mean that the AP will see the client devices. So yes, pushing the transmit power to the maximum will technically give you a better coverage for your wireless access point. And its role is to adjust how far the signal can reach. ![]() What happens when you push the transmit power to the maximum?īefore anything else, if you don’t exactly know what the transmit power is or does, it’s a setting that you find under the Wireless section on your access point or wireless router. What other ways are there to improve my network?.TP-Link EAP660 HD Access Point Transmit Power.EnGenius ECW230S Access Point Transmit Power.Ubiquiti U6-LR Access Point Transmit Power.Should you leave the transmit power on auto?.Can a high transmit power damage the hardware?.What happens when you push the transmit power to the maximum?.But does it apply today as well or is it just a relic advice that’s no longer relevant nowadays? Let’s find out. The access points that I took out for testing.Įven so, I know that the idea to keep the transmit power to the highest level was a common advice more than ten years ago, when every WiFi device was powerful enough. At the same time, don’t forget that not all your clients have powerful WiFi adapters, so even if the AP signal reaches them, that doesn’t mean that they will be able to reach back. That’s because while it’s true that a higher transmit power will increase the range, it also means that the wireless access point is going to interfere with other APs and the other way around.Īt the same time, I won’t deny that in a very noisy area, pushing the transmit power for your AP to the maximum will allow your far-away clients to actually connect to the network. If you’re in the middle of nowhere, you could have some fun pushing everything to the maximum, but in a crowded area, which includes all cities, you’re going to have a bad time and so will your neighbors. The correct answer to whether you should change the WiFi AP transmit power depends on the network density and the amount of interference.
