Wireless Performance to ReadyNAS - at my wits' end...
I have been having problems with wireless access to my ReadyNASes for a few weeks now. I think I can trace the problem back to replacement of my old router and access point with new stuff. The p...
I have now tried using the WNDR4500 as a WAP - better performance on that. t delivers twice the speed on both Write and Read, at 8.9Mb and 5.6Mb respectively.
Still scratching my head why the Read speeds are slower than the Write on this machine, but this is at least performance I could live with.
I've checked the logs on the access point (WNAP320) to see what's happening and it keeps deauthorising and then reauthorising the PC. This seems to be something a few others have an issue with and I'm hoping there will be a solution from the AP forum.
Here is the last Disk SMART log - can't see anything suggesting near death....also, I did notice a lot of errors involving "file does not exist" in the httpd_errors log, if that means anything much. I attach a sample of that at the end.
