Replacing my ISP's router was the single biggest upgrade I made to my home network

For most of the last five years, I had been using my ISP's Wi-Fi 5 router, and honestly, it wasn't that bad. The speeds were fine, the range was decent, and I didn't have too many devices to really stress the router. My PC was always on Ethernet, and my smart TV's streaming performance was decent on Wi-Fi. However, in the last few months, my home network underwent significant changes, which finally revealed the limits of the router. I added new devices to the network, moved my home office to a room further away from the router, and started streaming uncompressed 4K media from my Plex server to my TV. My ISP router failed to provide adequate coverage and performance for my new home setup, which is why I finally switched to an aftermarket router. I got better coverage without adding a mesh network Wi-Fi 6 finally covered my entire house Moving away from my ISP's Wi-Fi 5 router, I had a few different choices in front of me: buy a Wi-Fi 6, 6E, or 7 router. I picked a Wi-Fi 6 router to save a few bucks, and because Wi-Fi 6E or 7 would not have made sense on my 200 Mbps plan. Besides, none of my devices could actually make use of Wi-Fi 6E or 7 to justify the expense. For reference, the Wi-Fi 6 router I bought cost four times less than the cheapest Wi-Fi 7 router on Amazon. After the initial setup, it was time to measure the actual difference to my home network. I knew my network throughput wouldn't increase since my internet plan was unchanged. That said, I had hoped to solve the biggest problem on my previous router: signal range. My home office was now in the furthest room of the house, and the older router could barely cover the room. The new Wi-Fi 6 router increased the throughput to the room by eight times. From an abysmal 4.5 Mbps to a more-than-usable 36 Mbps, my smartphone and laptop usage in the room saw a dramatic improvement. The latency also improved noticeably. The Wi-Fi 6 router's improved signal range saved me the cost of buying a mesh network. I can delay the investment for a few more years, unless I move to a larger house, at which point a mesh network might be cheaper than a new Wi-Fi 7 router. I finally upgraded to modern Wi-Fi Basic features came late to my network Better coverage wasn't the only improvement to my network. I had been living with a Wi-Fi 5 router for almost five years, deprived of the features most users would consider commonplace. My older router lacked OFDMA and proper MU-MIMO, which naturally contributed to increased latency compared to a Wi-Fi 6 setup. Changing the router got rid of the occasional slowdowns that popped up whenever network activity was at its peak. I also upgraded to WPA3 encryption, leaving the outdated WPA2 standard behind. The latter forces a single network password for every device, and it's susceptible to brute-force attacks. Hackers can also use key reinstallation attacks by exploiting WPA2's 4-way handshake vulnerability, intercepting your internet traffic. So, a new router not only improved my network range and latency, but also made it more secure. I can freely tweak my router's settings I have control over my network Lastly, I now have full access to all my router settings on the admin page. Previously, my ISP locked down major settings like QoS, DNS servers, and VLAN, preventing me from customizing my own Wi-Fi. With my aftermarket router, I was able to use custom DNS servers to minimize lookup time and shape my traffic using QoS settings. Using a separate VLAN, I was able to isolate my slower smart home devices from my high-priority devices. There are other ways aftermarket routers allow you to tweak your Wi-Fi, namely transmit power and beamforming. The former can reduce interference from neighboring networks, while the latter can focus directional signals toward active clients. None of these settings were available on my ISP's router. Most importantly, I can update my router's firmware when I want instead of depending on the ISP to push delayed updates. TP-Link AXE5400 Tri-Band Router (Wi-Fi 6E) If you want a great Wi-Fi 6e router but don't want to spend a whole lot of money, check out this one from TP-Link. Most users don't realize their ISP's router is a huge bottleneck ISPs typically push outdated routers on users, delay crucial firmware upgrades for years, and lock down most of the settings on the admin page. You're using an under-equipped router that's crippling performance, compromising security, and limiting what you can do with your network. Switching to an aftermarket router is something everyone should seriously consider.
