Hi,
I have a WNDR3400 (DD-WRT v3.0-r30631 mega) connected to a R7000 AP (stock firmware) in client bridge mode talking over 5GHz network (2.4 is disabled). I have a NAS hard wired to the R7000 and having problems with uploading to the NAS from PC hard wired to the bridge. When I am copying something from the NAS to the PC I get about 8-10 MBps speed but copying from PC to NAS is slow around 2-3 MBps. I followed client bridged guide in the wiki to set it up.
In step 26 some folks said using operating mode as Router instead of Gateway. I tried that as well but the result is not much different.
Anything obvious I am missing?
Could be a bottleneck somewhere on the WNDR relating to CPU speed or file system. What is the nas drive formatted to? From what I've read ddwrt prefers ext2/3/4. Anything else takes a performance hit.
Paravox, the NAS is not connected to the WNDR, it's connected to the primary AP (R7000). Also, its not a USB drive but a standalone NAS server (DLink DNS-325).
As an extra test, I connected my laptop direct to the R7000 router by Ethernet cable and tried to copy a 2GB file to the NAS. Got a speed of around 10-12 MBps, so it rules out any write slowness on the NAS part.
I have a similar setup except with a WNR2000 acting as a repeater bridge to an R7000 over 2.4ghz, both running dd-wrt. When I'm copying files directly to/from the R7000 over 5ghz, I get 10-13 MBps. When I'm connected to the repeater bridge (wirelessly), it crawls at 1 MBps up and down. I have not tested things hardwired but I feel the primary limiting factor is the older (300mhz) cpu of the WNR2000, while the secondary factor is the heavy 2.4ghz interference in my area.
