最近我们收到反馈说我们的路由器无法与 T-Mobile 正常配合使用，例如没有互联网或只能获得 IPv6 互联网等。我们创建了一个测试版固件来修复并提高性能。
步骤 1 ：打开网络浏览器并转到 http://cudy.net 或 http://192.168.10.1。输入密码登录。
详细信息请参阅如何登录Cudy路由器的Web界面？
第 2 步：进入高级设置->固件，升级下面的测试版固件。 
LT18 固件： Cudy LT18 软件下载

步骤 5 ：转到常规设置-> 4G/蜂窝。
1. 设置网络模式为仅4G

“Dear Cudy Team,
I wanted to share my experience regarding the latest firmware for the LT500 V2. I had been using version LT500V2-R25-1.14.26-20220801-152148 for some time without any issues. Recently, I upgraded to the latest firmware version, LT450-LT500-LT500DV2-R25-2.1.1-20240419-090237."
@Rebecca,
Thank you for contacting Cudy support team. You can download the firmware on the website. https://www.cudy.com/pages/download-center/lt500-2-0
But for now, there is no OpenWRT firmware on OpenWRT forum. So I think you can’t update the router to the OpenWRT firmware.
“I own a Cudy LT-500 v 2.0 router amd am requesting the latest beta version of the firmware for this router as well as the latest releases of all applicable software necessary to install OpenWRT on this device. None of the listed download links referenced in FAQ are accessible. Thank you in advance.”
Dear Cudy Team,

After using version 2.1.1 for about a month on the T-Mobile network, I began experiencing frequent disconnects from the cellular network, usually several times per day. To address this, I have rolled back to version 1.15.28-20230410-094349 and will monitor if the problems continue.
I wanted to report this issue regarding version 2.1.1 and provide feedback. Thank you for continuing to create excellent routers!
