Hey there, friends. I just changed my internet service and upgraded to Frontier’s FibreOptic Gig Service, which promises speeds around 940Mbps download and 880Mbps upload. But when I run speed checks on my phone, I’m getting only a third or half of what I expected. The person who installed the fiber box told me not to use the ISP router because it might slow things down, so I bought a new one, but still haven’t hit the speeds I hoped for. The router I got recently is the ASUS ROG Rapture GT-AX11000 802.11ax Tri-band Gaming Router, which should handle my needs well. I’m not familiar with WiFi details or what might be slowing me down, so any advice would be greatly appreciated. Here’s some info that might help:
- My area is Southern California, and fiber is generally accessible nearby.
- The technician mentioned “GPON” in my neighborhood, but I think they meant “XPON.” That could affect performance.
- The device I installed (the ONT) connects through coaxial cable, Ethernet, then to the router. I’m curious if this setup impacts speed.
- I performed three speed tests using an iPhone 12, all within close proximity to my router, but the results were disappointing. Screenshots are attached for reference.
Any insights or suggestions would be super useful. Thanks!
It's been confirmed for Wi-Fi. I checked the connection using a device connected via cable to ensure stability.
From my point of view, it’s better to use the ISP router. If I’m experiencing slow performance, I’ll call them three times a week just to annoy them and get a big voucher or a discount on my bills each month. It’s a trick, but it works well. After all, reputation is what keeps the company paying me.
I faced the same problem until I purchased an Ethernet cable. I used Cat6 and achieved optimal performance right away.
You hadn't managed to fix the WiFi performance before, so you ended up relying on Ethernet for your connections.
Apple likely isn’t using the highest quality WiFi adapter available for phones. Typically, WiFi performs better on desktop computers or maybe laptops, while mobile devices tend to have more restrictions. The iPhone XR, for instance, was reported to reach speeds around 300 to 400 Mbps. That might point to a limitation in that case. Ultimately, the performance hinges on both the phone’s WiFi adapter and the router’s chipset. Although WiFi is considered a standard, variations exist among chipset manufacturers, affecting speed. Intel is generally regarded as a top choice for WiFi chipsets. It’s also important to consider whether 2.4 GHz or 5 GHz is being used. 2.4 GHz offers broader coverage but slower speeds, and it’s often shared with other devices like Bluetooth and cordless phones, causing interference. Microwave ovens broadcast on the same 2.4 GHz frequency, which can disrupt WiFi signals. Routers usually operate at around 100 milliwatts, whereas microwaves emit hundreds of thousands of watts. Moving through walls reduces both range and strength, but 5 GHz provides less coverage yet better penetration through obstacles. You’d rely on 5 GHz if you want a stronger signal, but be prepared for more interference. 2.4 GHz is best suited for non-essential devices or those where 5 GHz isn’t viable. Also, internet service providers rarely promise consistent WiFi speeds, and some ISPs like Frontier are known for poor performance. Their history with DSL and FIOS acquisitions has left them financially strained, which might explain their unreliable service.
When upgrading to 1Gbps internet, many overlook whether their router can handle those speeds and if their existing WiFi can support them. ISPs often supply all-in-one devices for this purpose, but they’re limited to wired connections because wireless is affected by numerous distractions. Most consumer routers in the budget range can’t match these rates, leading to significant bandwidth loss if you use your own hardware. In such cases, rely on the ISP’s equipment. The GT-AX11000 should perform well in this situation.
You must avoid testing speeds on a mobile device; instead, connect via a wired link (Cat5e or better Ethernet) to the AX11000 to confirm those speeds remain stable at 940Mbps. For WiFi performance, configure it correctly—use Ethernet over Cat5e or higher, disable interference on the 5GHz band, enable WPA2/3-AES security, and ensure clients support dual-band WiFi 6. With proper setup, you can reach link rates surpassing 1Gbps, fully utilizing your connection.
WiFi 5 can get near 1Gbps on some devices, but this usually requires both access points and compatible clients with robust multi-stream capabilities—rare for consumer hardware. WiFi 6 not only boosts the theoretical maximum but also supports many simultaneous connections, improving client-to-AP and client-to-client speeds.
Additional tips: avoid placing the router in a corner or at the edge of your home; position it centrally and high, and keep it clear of obstacles that block communication.
Even with WiFi 6, my Galaxy S10 reaches up to 750Mbit on my LAN. In reality, WiFi in my home never goes beyond that speed, no matter the settings. The main difference is I can connect using an 80Mhz channel on WiFi 6, while my laptops require 160Mhz on WiFi 5 to match the same performance. You’re lucky if you get close to Gigabit speeds—only when you’re in the same room, directly in line of sight, on a clear channel with no interference. On average, it usually delivers 200-400Mbit, and right now it’s around 582Mbit, which matches what many people are experiencing.
