Attached is a log from my RV260W, covering a recent nine-hour service period. There are 938 entries in the log, 800 (85%) of which are "ampdu_dbg" warning messages. Extrapolating this to a 24-hour period would mean that the router is cranking out more than 2000 of these messages every day.
Frankly, I find this behavior from the unit distressing and discouraging. The noise level in the logs is so high that it is very difficult to search through them for meaningful information. Other users have reported this issue, too, with the reports going back months (and spanning firmware updates). Suggested workarounds have been to disable features on the router, like WMM. That, of course, is not a solution.
So, again, I ask: is AMPDU frame aggregation broken on the RV260W?
UPDATE: Attempted to get an answer to my question using the online chat support available to small business customers. Spent thirty minutes staring at a window telling me to hold for the next available agent before I was forced to resume my normal life. I had really hoped that paying the premium for equipment from a big-iron manufacturer would result in better post-sale service and support than what I'd received in the past from consumer-oriented companies. It's beginning to look like I was wrong about that.
FURTHERMORE: I called Cisco's telephone support line, only to discover that, since I'm an individual end-user (unaffiliated with any company), Cisco's support ticket system wouldn't allow a ticket to be opened for an equipment owner not associated with a company. The agent I spoke with (Albert) really tried to be helpful, but the ticketing system refused to let him open a case for me (as an individual end-user). He suggested I go back to the company I bought the equipment from (Provantage) and have them open a support ticket on my behalf. Too late in the day to talk to Provantage now. But, stay tuned...
LONG STORY SHORT: After several go-rounds with Cisco and Provantage via e-mail and telephone, I decided to review my warranty again. In addition to the Limited Lifetime Hardware Warranty, the warranty provides "access to technical support during local business hours, 8 hours per day, 5 days per week...for a period of one (1) year from the date of purchase of the Cisco product."
Everything's golden, right? Well, not really.
All the way down at the bottom of the page, in a section titled "Service Assistance," is the following language:
"If you have a Cisco SMART Net Total Care service program or other maintenance agreement, request service under your agreement. You can purchase maintenance contracts from your local network supplier or from Cisco directly.
"Call the Cisco TAC line if you have contracted for this service. TAC support is not available as part of warranty alone." (emphasis added)
So, you might ask, what "support" is provided under the terms of the warranty? As near as I can ascertain, it is limited to whatever documentation for the product Cisco publishes online and whatever information the equipment owner can glean from the Cisco Community forums.
That's it.
So, if you need real technical support, get out your checkbook...
I'll leave it as an exercise for the reader to square the language at the beginning of the warranty with the exclusion found at the end.
