Hey everyone, I've been experiencing slow upload speeds—around 1Mbps—despite normal download speeds. I've reset both the router and modem, tried connecting directly to the modem, and even reached out to Xfinity support, but nothing has helped. Any advice would be super helpful.

You're paying for both download and upload speeds, and you're checking performance by measuring the time it takes to transfer files.

Using the Chrome-based speed test for 600/25 results.

Open the Ookla app and check your connection type.

You're still experiencing similar issues with the wired connection.

Is your router running the newest software update? Also, remember to mention someone when you reply so they receive a notification.

Are you connected to a specific network? Are there other devices or users accessing the internet concurrently during these tests?

Verify your modem signals. It seems there could be excessive power on your upstream channels causing problems. Access the modem diagnostic pages via 192.168.100.1 Upstream Bonding Channel Value Channel ID 1 7 3 2 Frequency 35800000 Hz 16600000 Hz 23000000 Hz 29400000 Hz Ranging Service ID 11859 11859 11859 11859 Symbol Rate 5.120 Msym/sec 5.120 Msym/sec 5.120 Msym/sec Power Level 44 dBmV 43 dBmV 43 dBmV 43 dBmV Upstream Modulation [2] QPSK [1] 32QAM [3] 64QAM [2] QPSK [1] 32QAM [3] 64QAM [2] QPSK [1] 32QAM [3] 64QAM Ranging Status Success Success Success Success You're after the upstream details. Expect readings above this range, as levels over 54 may lead to slow connections or disconnections.
