5GHz Wi-Fi two routers setup
5GHz Wi-Fi two routers setup
I recently relocated with a friend who still uses an older Comcast modem/router that only supports a 2.4GHz Wi-Fi connection. To resolve this, I purchased a dual-band router offering both 2.4GHz and 5GHz bands. I connected the new router and created a separate network. After some adjustments, I disabled the 2.4GHz option on the new device and set up a separate LAN/WAN router. However, that setup didn’t resolve the issues. I switched it to access point mode, but I’m still experiencing random disconnections, lag during gaming, and unexpected restarts from applications. Overall, the 2.4GHz network causes noticeable delays on the main router. I understand the desire to keep the old network intact, as changing everything would be disruptive for my friend and his mom. Could there be a way to improve the 5GHz performance while maintaining compatibility with the 2.4GHz signal? Please see the attached photo for reference.
The main issue is my friend and his mom want to keep the old setup running. If possible, I’d just use the Comcast router as the modem only. I didn’t see your second part either. I’m not sure what the intended speeds are, but with 5GHz it reaches up to 21MBs when working. Edited May 24, 2019 by guiltyspartan98
Does your room have a 5GHz router? 5GHz offers a much shorter range than lower frequencies. It performs better nearer devices, though its strength drops rapidly with distance.
They are named differently but share a similar setup point—using the same gateway address for the primary router. The home A222 runs at 2.4GHz, while the R6S operates at 5GHz.
The double routing problem seems familiar. It’s not ideal, but swapping the cable from the Comcast modem into a LAN port on your new router instead of the WAN port adds a switch rather than a router. This avoids extra overhead and protocols. A dedicated 5G AP would be better, though that option is no longer relevant at this stage. DHCP should handle itself in the Comcast modem, and you shouldn’t notice much change in speed.
You should take these steps:
1) Turn off DHCP, Firewall and similar features on the TP Link Box.
2) Assign a different IP address to the TP Link router’s network settings—avoid using the default Comcast DHCP range. Adjust it to something like 20.0.0.2.
3) Link the TP Link router’s LAN port to the Comcast gateway’s LAN port. Consider turning off the 2.4 GHz radio on the TP Link device if it will also act as an access point, reducing interference in that frequency band.
