[操作疑難] networking問題

ilike911

我部tplink router TL-WR841 flash左dd-wrt
LAN個4個port互相ping唔到, 係destination host unreachable

但係用wifi又ping到個d機,有無師兄知道點解?
我troubleshoot左成日都搞唔掂,唔該晒大家><


*全部都PING到ROUTER IP
*試過熄晒WINDOWS FIREWALL

LAN ping唔通?除非4個port都唔同vlan。

係咪同一個lan先

事源係我之前隻TP LINK ROUTER (TL-WR841 ver7 flash左ddwrt)神神地,
之後換左隻同一型號但係ver9既,之後flash埋ddwrt, set好晒之前既野之後繼續用.
今日想B機remote去A機,發覺唔得,原來PING唔到A機
p.s.我平時係C機remote desktop去A機係OK既,又開到D share drive,

BTW 我整左張圖,
另外想話wireless既機可以互ping,
點解lan port既pc互ping唔到...
真係好奇怪/__\

有冇dd-wrt入面networking既config睇睇?

aconfuseman

1) the ip of PC is set by yourself or by DHCP from the router ?
2) test whether the PC (connect to LAN) can ping the notebook (wireless)
3) record the mac address of each device (PC and notebook)
4) check the mac address record in the router (through the GUI of router)
