You're experiencing lower-than-expected Wi-Fi speeds even though you've applied DD-WRT. Since your phone is a dual-stream device, it should handle around 866 Mbps locally. The discrepancy suggests an issue with the network configuration or interference. Consider checking signal strength, router placement, and potential channel conflicts.
Use another wireless gadget for testing. If the problem continues: Look for signal clashes (many nearby access points, etc). Position the device close to the router to remove distance effects. However, interference is usually the main concern following a phone.
The laptop advertises a speed of 400mbps yet performs much more slowly than expected.
It seems you're uncertain. Would you like me to reset the router?
The limit for 866 is capped at 5 GHz. What’s the deal? You won’t hit the real maximum with Wi-Fi—it’s just not possible. The numbers are theoretical. Be grateful if you manage about two-thirds of the speed. 5GHz offers less coverage and penetration. Things like thick walls or concrete barriers make it worse. Even though 5GHz is generally free, some devices use it—like cordless phones. In the US, weather radar also employs it, and the government shares parts of the spectrum, which could be a problem.
The challenges become irrelevant when the gadget is close to the router. Also noted, the phone supports up to 866 Mbps while the router handles 1300 Mbps. EDIT: My approach wasn’t clear, but my checks now operate around 750 Mbps, which feels more accurate. Need more details. Updated August 29, 2018 by Colt_0pz
I mentioned the speeds on the box are "THEORETICAL." You won't reach the actual top speeds. Also, a 1300 Mbps connection on the box equals a combined 2.4 and 5 Ghz frequency. 867 Mbps represents the upper limit that most phones and laptop networking cards can handle, again just a theoretical maximum. It's similar to this: an 8x4 cable modem should be able to achieve around 343 Mbps according to the Docsis 3.0 guidelines. Nevertheless, most cable companies only provide up to 200 Mbps on the modem. Since these standards are theoretical, in practice they rarely reach such performance. About three-quarters of 866 is roughly 570 Mbps, which might be closer to what you can expect in real life. You might also find some routers and wireless cards using specific standards to boost speeds. Unless both the card and router adhere to those standards, you may not approach full capacity. Also, as previously noted, interference from other devices could affect results. Radar is known to operate in the 5 Ghz band, while DFS allows radar and WiFi to share the same spectrum.
If that's true, the box would display 1900mbps (actually 1300mbps on 5AC plus an extra 600 mbps on 2.4N). I'm sure my Galaxy S7 is a dual-stream device, so it should handle up to about 866 mbps theoretically. I'm not measuring the actual internet speed, just local performance. Since I can't reach those higher numbers, I expect around 750 mbps—which is within an acceptable range.
