Firmware problems and dropped access
on June 29, 2013
Bought this to implement for a small business of ~20 employees using a variety of devices (PCs, Macs, android and IOS devices) and faced nothing but a steady stream of problems with performance and stability.
First and foremost, pay attention to the product description. It is capable of supporting dual bands (2.4 OR 5 Ghz) but NOT simultaneously. One must choose one band or the other. I can somewhat forgive that. What was truly disappointing however, was the unit shipping with firmware revision 1.26 and there are a slew of performance problems with this firmware version . Sessions for mobile devices are randomly dropped and as time progresses disallows association of those devices. Looked for new firmware on the website only to realize the latest "stable" available release on the site was 1.25. Contacted support for assistance and they suggested downgrading the hardware to the version posted on their website, 1.25 (current as of 6/29/13).
The unit was downgraded to 1.25, (this is a major fail to have to perform this procedure). The problem still persists, but instead of failing every 36 hours, it fails between 48-72 hours. After that window occurs, power cycling the unit is the only means to resolve problems, (second major fail). In addition, while on the "stable" code some mobile devices, most notably apple devices (computers or i-devices), but not limited to, have difficulty maintaining connectivity. The logs show repetitive association/deassociation events, with reason code 8. Typically reason code 8 is a client leaving an AP due to load balancing. The problem with this scenario, there is only one AP in this setup and load balancing is NOT enabled!
Further debugging should be done with a variety of devices against various wireless chip manufacturers (some perform MUCH better than others, and this hardware seems particularly sensitive, but either way, I do not relish functioning as QA for D-Link when I am a paying consumer. Either their process, testing, or both are broken as product should NOT have been released with 1.26 when it "appears" to have not been thoroughly tested. This is truly sad this product is so problematic. I deploy many of their other products for small business owners, but wireless has always been problematic and apparently continues to remain so. One would expect this type of rubbish for their consumer product line, but not their business line. Highly disappointed, and migrating clients to another vendor's wi-fi solution.
I would give it only 1 star if it weren't for the fact the user interface is actually decent. Too bad the meat and potatoes of the product, the IMPORTANT stuff, don't match up to it.
