One Tuesday morning, her network dropped to 30 Mbps. The 5G icon was gone. Only 4G remained. After rebooting, resetting, and repositioning the router, nothing worked. The 5G band (n78) she relied on had simply vanished.

Frustrated, she logged into the admin panel: Firmware Version: V1.00(ABUV.0)b12 . She then visited a niche ISP forum. There, she discovered the truth: Three UK had pushed an Over-the-Air (OTA) firmware update overnight. The new firmware (b13) wasn't buggy—it was intentional . It had disabled specific 5G bands to prioritize traffic for newer, more expensive plans. Her "unlimited" plan was now throttled in firmware, not just policy.

The screen flashed. The router rebooted. And there it was—the 5G icon, solid as a rock. 620 Mbps. She had won.

In late 2023, Sarah, a network enthusiast living in a rural UK town, finally got her hands on a Zyxel NR5103E. It was the crown jewel of 5G routers—3.5 Gbps speeds, carrier aggregation, and a robust Qualcomm chipset. Her Three UK SIM card slid in perfectly. For three months, it was bliss: 600 Mbps down, 90 Mbps up.

The Tale of the Disappearing 5G: How NR5103E Firmware Became a Double-Edged Sword

But the story doesn't end there. Three weeks later, the router forced another update. Why? Because the NR5103E’s modem firmware is signed to the IMEI of the device. Even after downgrading, the carrier’s network rejected the old firmware’s authentication handshake, eventually locking the SIM.

“I’m always seeking the next big thrill”

Me in a word: Exploratory

The first 21 years of my life were a mix of travel, sports and chasing academic excellence. As a child, I enjoyed jet skiing, bungee jumping and a few venomous pets. I’m still always seeking the next big thrill, like rock climbing and cave exploration.

Since leaving university and surviving the COVID years, I’ve developed my skills across different fields, from education to private healthcare, with a keen interest in human biology and education. nr5103e firmware

To relax, I watch old war movies or series, and shows like Sons of Anarchy and The Wire. Cooking was a big part of my childhood and I’d always help my parents prepare meals. I’ll bake anything with chocolate!

My wilderness survival buddy would be my dad. He’s a DIY expert, with basic wilderness survival skills. I once had a narrow escape outdoors: Venturing off the path on a solo hike, roasting in midday sun, suffering from dehydration, leg cramps and an encounter with a juvenile cobra. (I survived.)

Some everyday things that really annoy me are the morning traffic rush – and people being indecisive at the drive-thru window. One Tuesday morning, her network dropped to 30 Mbps

My bucket list destinations? Thailand, for rock climbing and base jumping, and Burma, for Lethwei (Burmese bare-knuckle boxing).

I think the human race needs a greater focus on work-life balance. Spending more time enjoying the little things, whether sport, art or music would help everyone live better, more fulfilling lives.

If I could change the law, I’d ban farm-raised lion hunting, and I’d allow a years’ paid parental leave for all new parents. She then visited a niche ISP forum

Outside of work, I juggle sports, cooking and taking my dogs out for regular walks.

My work family is supportive and engaging, always available to bounce ideas or chat. Learning Curve is the best work family ever, with an unparalleled culture. I like the freedom and flexibility to explore new and creative avenues – and the endless coffee (Yay!)
