ASUS RT-N56U 問題

本帖最後由 chinghinkee 於 2015-10-16 14:24 編輯

是咁的,小弟用N56U LAN port 出3部電腦,就係其中一部電腦上唔到網(LAN port 綠燈閃兩下停一陣再閃;電腦話我冇插線)。試過換條短d既LAN線又上到網。奇怪系條長LAN線插第2部電腦可以正常運作。又試過長LAN線由HG8045入電腦都可以上網。

Config:
HUAWAI HG8045 => N56U => Computer x3

究竟點解條長LAN線由N56U出就死?
已經更新N56U 同電腦LAN card firmware.
Thanks!!!

當PC------router------ISP入屋wall plate 嘅2段線路出現568A同568B 兩種接法就會有你嘅問題出現,PC經router會上唔到網,但係PC直插wall plate(只用1段lan 線)無論568A或568B接法都會work

compare 下長lan線同短lan線(work果條)嘅顏色序列有無唔同,有唔同夾過長lan線2個rj45頭,顏色序列跟返短lan線

可以試下:
1. Upgrade firmware to latest version, then press the hard reset button for a few seconds. Then reconfigure the ssid & pw
2. Turn WPS off
3. Change 2.4 G to 20 mhz (to avoid interference from neighbourhood). It looks the bandwidth is narrower but you will get less interference because it not overlapping with other signal around you, so its much stable due to less packet loss.
4. Use WPA personnal (AES) as encryption.
5. Enable wmm
6. Install an app called Wi-Fi 分析儀 to your android or i phone, check which channel is most free around your home.(it can chack 2.4G and 5G)
7. Manual assign the more free channel (choose between 1, 6,11 or 13 Note: some device does not recognize channel 13)to the router.
8. The 5g signal has less interference by others, so you can set it to 40mhz and assign a free channel to use. Its much faster to use 5g if your device support 802.11 5g and its close to the router.

cable tester 只會話你知8 條線通唔通,同埋條線係striaght thru定cross-over, 係認唔到568A or 568B顏色序列架
