Does anyone else experience a significant loss of Verizon Fios advertised speed when using the Flint 2 router? I just purchased this router and upgraded the firmware to 4.6.8, hoping it would fix the upload speed issue. However, I'm still seeing around 900 Mbps download and only 200 Mbps upload, whereas my advertised speed is 1000 Mbps for both download and upload.

When I connect my laptop directly to the ISP, I get about 900 Mbps for both download and upload, so I know the issue isn't with my ISP connection.
Is this a known issue with the Flint 2 router? Is there any available fix? I really want to like this router, but losing that much upload speed is disappointing.
I just reset the router to default and did as you said with no other settings. The speed test looks the same as it did with significantly lower upload speeds.

My ISP modem provides a 1 Gbps upload and download link. When I connect my laptop directly to the modem, I achieve the full 1 Gbps upload and download speeds. However, when I connect the modem to either of the 2.5 Gbps WAN ports on the Flint 2 router, I only get around 900 Mbps download and 200 Mbps upload.
Here are the details:
ISP Modem: 1 Gbps upload and download
Router: Flint 2
Connection: 2.5 Gbps WAN ports on the router to the ISP modem
Results: ~900 Mbps download, ~200 Mbps upload via router; 1 Gbps upload and download via direct laptop connection
I plugged my laptop directly into one of the LAN ports and ran speed tests, which showed better upload speeds of 500-600 Mbps. However, running the speed tests directly on the router reported lower speeds for some reason. I was following another post on this forum GL-MT6000 Slow Upload speed, which led me to think that running the speed test from the router, being "closest" to the ISP modem, should report the best results. In the end, it seems that the endpoint connected actually matters more.
If not try without it, since vpns get throthled alot by cdns and even sometimes censored due to malicious activity, when performing a speedtest often you hit multiple ip, it is possible something slows it down.
To me it looks like a stable connection, i think your router is running some kind of QoS control, which in the gl firmware is present called /etc/init.d/gl_qos, otherwise you see 100/100 for both download and upload, or 100/200, for the last one the upload must be set lower maybe also for 100/100 has to do with latency.
^ also some isps lower it with intend, which can be understandable if they want to restrict malicious activity from its users, because 1gbs upload vs a 1gb server is a too easy take, some isps are smart and artifically lower it, but they must list that on their product.
When you connect to the router via a device, your WIFI speeds in a Speed Test will be limited by the speed and quality of your connection. If I connect to the router via a 2.4 Gbps (160 Mhz channel) WIFI 6 connection, I get full posted Internet speeds. If I connect via a mobile phone or tablet with a WIFI 5 connection, I won't even get 1/2 of the rated speeds.
A WIFI connection has a fair amount of overhead, approx 30% on WIFI 6. That means that on a 1 Gbps wireless connection you would only get 700 Mbps of data throughput with 300 Mbps used for protocol signaling.
OpenWRT has 2 speed test apps that can be run from command line directly from the router so you can see the speeds received directly at the router, which is the most accurate way of testing.
I am also having the same issue when my laptop is connected via WiFi (same room). My download speed hits 1 gbps but upload is limited to 1 or 2 mbps. When connected via LAN, the upload speed improves to 500 mbps instantly. Any fixes?
Update: turns out to be an issue with my computer. I tried another laptop and a mobile device, both speeds are good. I love flint 2, using it as a VPN server.
I bought the Flint 2 to replace my TP-Link AC1750, but after many tests the Flint 2 consistently only achieves upload speeds of 100 mbps while the AC1750 achieves upload speeds of over 300 mbps. Download speeds are both around 280 mbps. The tests were both done over wifi. I'm on Verizon home internet.
Is there a fix for this? If not, I'm going to return the Flint 2.
