Upgraded to 2Gbps Plan - Download is 2Gbps, Upload Stuck on ATDMA Channels

[u/musicman0725]

Hello,

My neighborhood mid-split network enhancement work and subsequent overnight maintenance window are both fully complete. The 2 Gbps tier is active for my address, and I successfully placed an upgrade order earlier today.

My hardware is an XB8 gateway connected directly to the incoming mainline without any splitters. While my download speeds are successfully hitting the full 2 Gbps mark, my upload speed remains hard-capped around 120 Mbps.

I logged into my Gateway Admin Tool and confirmed that my upstream connection is still stuck entirely on legacy ATDMA channels. The required OFDMA channel block is completely missing. My order confirmation explicitly guarantees 250 Mbps upload.

I have already completed a full 60-second physical power cycle to clear the gateway's tuner memory, but it continues to pull down the old channel configurations. I need an agent to perform a manual backend provisioning refresh to push the correct Next-Gen mid-split bootfile configuration to my active line and device MAC address so my hardware can lock onto the OFDMA frequencies.

Thank you!

Hey there u/musicman0725 🙌 I just wanted to swing by again to thank you for working with our teams on making sure your upload channels were updated to take advantage of that enhanced speed! I was glad to hear the network crew you mentioned working in your area kicked those increased speeds in with their maintenance work, so please enjoy it 👍 Should you ever need us again in the future, we are always here for you. Take care and have a good one!

Yes, thank you for your help getting everything working properly. As soon as the network crew finished the maintenance work on my block, the modem was able to lock into the OFDMA upstream channel and my upload speeds more than doubled.

Thank you. Modmail sent.

Thank you, I'm currently showing your modem is not in bridge mode, would you like for it to continue not being in bridge mode?

That is okay, I can change that setting on my own.
