WiFi repeater supporting two frequency bands plus a single-band router
Hey everyone, I’m trying to boost my WiFi coverage onto the terrace using a repeater. But I run into an issue: my router only supports 2.4 GHz, which limits bandwidth. I’ve looked into whether getting a dual-band repeater (supporting both 2.4 GHz and 5 GHz) would solve this problem by letting it communicate over 2.4 GHz while creating its own 5 GHz network. Someone here might have some advice. Thanks ahead!
The repeater would promote the network across both 2.4GHz and 5GHz frequencies, yet it would need to forward the data back through the 2.4GHz channel. This means the available bandwidth for connected devices would remain only half of what they would experience directly from the router.
They might still be linked to the 5GHz network of the repeater even if they are not directly connected.
the dualband operates on two frequencies—2.4 ghz and 5 ghz—to boost data flow. When a device uses only 2.4 ghz, the repeater repeats that signal; it doesn’t add extra channels. The 5 ghz side can create its own signal independently, but it relies on devices supporting 5 ghz. Coverage is weaker at higher frequencies, especially through walls or furniture. What gets sent depends on what the source provides from the 2.4 ghz link. For maximum reach you need a 2.4 ghz network, while 5 ghz offers speed but only up to about 150mbps under strong signals. If you aim for faster speeds, 5 ghz is better, but expect around 80mbps after roughly six meters. AC connections are built for speeds over 500mbps, so 2.4 ghz is limited to around 150mbps if conditions are good.
Yes, you're right. To reduce bandwidth loss, you can either buy a dual-band repeater or opt for an alternative solution instead of a standard WiFi repeater.
I believe you meant a dual-band router, but even then you'll likely experience slower performance from the repeater. Consider exploring a mesh system with a dedicated 5GHz band for backhaul, or opt for a more powerful router if possible—this is usually easier said than done. It's important to check the speeds your router provides on speedtest sites. If you're seeing around 10Mbps download, your current setup should work with the repeater, but it will limit the maximum achievable throughput. Unless you're doing local wireless file transfers, this might not be a significant issue.
I asked my ISP to turn off the Wi-Fi from my modem. Then I set up three routers around the house, each isolated from the others. This lets me connect the device I need wherever I want, control the Wi-Fi settings as I like, and place the router where I thought it was best. I’m not suggesting buying three routers, but positioning one well and using an Ethernet repeater instead of Wi-Fi could work really well in many cases—especially when city Wi-Fi is too crowded.
Sure, that makes sense. I'm also planning to upgrade my basement's WiFi while avoiding one floor of the house. I'm considering Powerline and setting up a mesh network for better coverage. That's why I'm aiming for a strong signal on my terrace and linking everything into a robust mesh system. Unfortunately, my current ISP speed is quite low, so it's not ideal to ignore the cutoff. But thank you for the quick replies!
In theory, a dual-band router can function as a WPS Client on 2.4GHz and then switch to broadcasting on 5GHz. This allows you to utilize the full bandwidth of 2.4GHz since it operates as a specialized client. However, most routers won’t support this setup. Therefore, for better performance, a dedicated mesh system is more effective, especially when using a separate 5GHz channel for backhaul to the main router.
