From what I've heard/dealt with this particular router and firmware there is no known issue that is wide-spread. I'm not trying to down play your issue as I really would like to help you though.
I'm not sure what considered as being "wide-spread" over at D-Link HQ, but I believe that with as many people here posting about the exact same issue
that just maybe, statistically speaking, many other people who don't post, do not know how to post, do not care to spend time posting, return the product immediately, or who simply drop the router off of their 5th floor apartment balcony and buy an Asus router instead because it's too light to use as an effective doorstop,
it may be more than just a single anomaly or two.
With that said, I really do like the feature set and design of this router and I have recommended it to many friends, family and business clients, however, most of them are complaining to me that their routers (WBR-2310) are having issues as have been mentioned in the many previous posts. This:
#1 Makes me look st*pid for recommending this router.
#2 Costs me time & money (when I have to drive out to some place to fix it)
#3 Frustrates me (and everyone else here) that we have been waiting for months (years?) to have a stable WBR-2310(amazingly loyal customer base who is even offering to help you (D-LINK)
to fix D-LINKS' problems.
I think that all we want is this router to meet (not even exceed) basic (advertised?) standards:
#1 It is stable
#2 Its features work they way they should (like the Wireless).
You mention that you would like to help us. People on this post have offered to help D-Link
in fixing this router. Help us by letting us HELP YOU
. Give us something to work with. Maybe the source code, more beta firmware, ways to hack the firmware, something.
If you really want to help, do something.
Give us contact info to someone higher up, or regular updates on issues being worked on, or give us some better diagnostics tools, or ways to load custom firmware (if possible). People on this forum are not st*pid or d*mb (like me for recommending this router). They are very intelligent, willing and capable to HELP D-LINK with this router.
Don't give us random switches to change on the router that we already have tried. Either you are just trying to waste our collective time, or the features are BROKEN on this router and NEED TO BE FIXED.
My patience with this router is down to the wire here, and I don't think I'm alone (or am I?). I will personally work with D-Link in my own IT lab, ON MY OWN TIME, to resolve this issue FOR FREE.
