这个猫支持ADSL2+吗,还有LZ的1M网速用这猫能下到160K左右,以前用阿尔卡特的能下到多少? 我现在用511开路由开UPNP,BT下载150K,很稳定,不高也不低
用这个在资源很多的时候170K,最低的时候155K,稳定160K
511用的FW就是论坛里最新的4.3.6.0
ADSL2+是支持的,请看这个,转载自

RTL8671/RTL8271
ADSL2+ Router SoC Solution
General Description
The Realtek RTL8671/RTL8671P are integrated SoCs featuring a RISC, an ADSL2+ Discrete MultiTone (DMT) datapump, a hardware ATM Segmentation and Reassembly (SAR), a 10/100Mbps IEEE 802.3 compliant MAC with Ethernet transceiver, and a PCI host/device bridge interface. Together with the Realtek RTL8271 (ADSL2+ Analog Front End), the RTL8671/RTL8671P provide a low-cost integrated solution for ADSL2+ CPE modem, router, or gateway.
The RTL8671/RTL8671P incorporate high-performance DSP technologies, optimized mixed-signal designs, and an efficient system architecture to provide a seamless WAN to LAN router controller. The embedded RISC network processor supports the MIPS I instruction set along with DSP extensions, and achieves a 200MHz clock rate in a six-stage pipeline to support layer 2, 3, and other upper layer applications.
