AC66U upload 慢過 download 問題

剛買左AC66U, 替換已用左幾年既Linksys WRT-610n

我最主要希望用佢加速notebook 同 NAS 既傳輸。以前用610n, 用5Ghz n network download NAS 既file最快只可以去到11MB/s 左右。upload 都差唔多。

換左AC66U, 其他不變下,download 同一個file 可以去到 39MB/s
但係upload 就仍然只得11MB/s 左右,有時重少左。

我試過將部notebook 直接插線落AC66U, upload 可以去到近100MB/s, 即係NAS 並唔係Bottleneck

想問下大家點解upload 慢過 download 咁多呢?

配備:
Macbook pro 13" late 2011, Core i7, 2.8Ghz, OS X 10.8.3, Plexter M5S 256GB SSD
(呢部機應該係支援5Ghz n, 3x3 MIMO)

DIY NAS, P8H77-I, 用Gigabit ethernet 駁去router, Ubuntu Linux, 用AFP protocol 傳輸(過往經驗, AFP 快過Samba)

PS Scan 過屋企周圍,無人用同一個channel.

Your notebook does not support wireless AC, meaning you are only running on 5GHz wireless N only.

Sure, I understand I am using N (5Ghz).
My problem is the asymmetry of upload and download speed.

download file 39MB/sec, 好懷疑係虛報
照計冇理由可以咁快 (假設你用450Mbps n)

notebook 同router 間距離大概十尺左右

Try Merlin Build

    裝左Merlin build 29, upload 快左少少,不過都只係14-15MB/s 左右,同download 重有好大距離。(用左Merlin build, download 都快左少少,突破40MB/s 大關)
