问题描述：买的是TP-LINK TL-WR740N，在公司用动态IP有线、无线均没问题，回家用PPPoE连接是总是提示“用户名或密码错误”而上不去网，也实验了提示的其他方法，如克隆MAC，均不行。拔掉设备直接将电脑与电信公司提供的猫连接，相同的用户名和密码每次都能正常拨通。请予以回复或发电子邮件至543796592@qq.com，非常感谢！ 以下是部分系统日志： 369 0374:PAP:密码验证失败. 370 0374:HENAN CNC authentication. 371 0375:发送PADI,请求建立连接. 372 0375:PPPOE_TAG_SVC_NAME=null 373 0375:The first service name is accepted. 374 0375:PPPOE: receive HOST-UNIQUE tag. 375 0375:接收PADO,AC-Name=GS-TS-YSN-BAS-1.MAN.ME60-16,AC-MAC=001882E253E9. 376 0375:发送PADR. 377 0375:接收PADS,Session-ID=0x11B4,AC-MAC=001882E253E9. 378 0375:LCP tx Req,MRU=05C8;Magic=000013B2; 379 0375:LCP RX Req,MRU=05D4;Auth=C023;Magic=09003662; 380 0375:LCP tx Ack,MRU=05D4;Auth=C023;Magic=09003662; 381 0375:LCP RX Ack,MRU=05C8;Magic=000013B2; 382 0375:PAP IDLE -> REQ. 383 0376:PAP tx Req. 384 0376:PAP:密码验证失败. 385 0376:XIAN Vnet authentication. 386 0378:发送PADI,请求建立连接. 387 0378:PPPOE_TAG_SVC_NAME=null 388 0378:The first service name is accepted. 389 0378:PPPOE: receive HOST-UNIQUE tag. 390 0378:接收PADO,AC-Name=GS-TS-YSN-BAS-1.MAN.ME60-16,AC-MAC=001882E253E9. 391 0378:发送PADR. 392 0378:接收PADS,Session-ID=0x12F5,AC-MAC=001882E253E9. 393 0378:LCP tx Req,MRU=05C8;Magic=00006ACB; 394 0378:LCP RX Req,MRU=05D4;Auth=C023;Magic=090039EF; 395 0378:LCP tx Ack,MRU=05D4;Auth=C023;Magic=090039EF; 396 0378:LCP RX Ack,MRU=05C8;Magic=00006ACB; 397 0378:PAP IDLE -> REQ. 398 0378:PAP tx Req. 399 0378:PAP:密码验证失败. 400 0379:HUBEI Vnet authentication. :(|2006-01-01 8:30:23 1824s| Tlb Load Exception Exception Program Counter: 0x00000000 Status Register: 0x0000f401 Cause Register: 0x10000008 Access Address : 0x00000000 Task: 0x80b8a8d0 "mud1_t0" Time = 2006-01-01 8:06:19 379s H-Ver = WR740N 5.0/6.0 00000000 : S-Ver = 4.17.7 Build 110128 Rel.60749n L = 192.168.1.1 : M = 255.255.255.0 W1 = PPPoE : W = 0.0.0.0 : M = 0.0.0.0 : G = 0.0.0.0 Free=5026, Busy=4, Bind=2, Inv=0/8, Bc=0/0, Dns=124, cl=448, fc=0/0, sq=0/0
