Ive owned a ReadyNAS Ultra 4+ for several years now, with little to no problems, however I'm now having a very strange issue. Every time my NAS is connected to the network, the entire network begins to crawl. And I do mean the entire network, both LAN and WAN. Page loads will slow down and even fail to load, accessing my mapped drives slows down, even wifi devices will slow down. I am positive it's the NAS causing the slow down because I can unplug the 2 cables and the network returns to optimal performance.

NAS is on the latest firmware, both network interfaces have static ip set inside frontview. I tried trading the Trendnet switch for a Linksys SE2500 and that didn't work. I have purchased at the time of this writing a bunch of cat6 cables from Monoprice.com to replace every cable I can to see if that will help performance.

What happens if you unplug one of the two ethernet cables to the NAS (leaving the other connected).

Ive disconnected one of the ethernet cables and my network seems to be working properly. However, won't this lower my read/write performance to the NAS?

Don't think so with that model or not that much.

Generally when you connect two cables that way you want to use a link aggregation protocol (for instance LACP). I think you might not have been doing that. LACP needs the switch to support it to.IseWise wrote:However, won't this lower my read/write performance to the NAS?Not for single user performance. If you have simultaneous users it might reduce performance a bit.

LACP needs the switch to support it to.Perhaps, I spoke too soon. It appears that the problems have returned. I tried connectly the NAS directly to the router and that didnt seem to help either. Ive had both ethernet connections connected before for quite some time to the same switch and haven't had issues before.IseWise wrote:However, won't this lower my read/write performance to the NAS?StephenB wrote:Not for single user performance.

Im wondering if this problem has anything to do with me recently switching ISPs. I recently upgraded from Centurylink DSL to Comcast cable. I checked Network > Global Settings > DNS settings were empty. I filled them in with my DNS servers provided by my ISP, but I am still have slow down issues. A have ftp running on the NAS. Could this be related?

ReadyNAS Ultra 4 is slowing down my entire network LAN & WAN

I'm thinking this is what might be causing me massive network issues with my ReadyNAS Pro as well. mdgm, are you able to help me out possibly as well?

OK, my NAS had been hacked...
