Nasty KRACK

This week’s networking crisis is that black-hats have found another way to violate your privacy. Called the KRACK exploit, it allows hackers to spoof WiFi protocol so as to break its encryption and read your traffic.

It’s worth pointing out that this is not just a zero-day bug in some manufacturer’s implementation—it’s a defect in the WiFi standard itself, and all WiFi (802.11) encryption is vulnerable to it. It does require a hacker to be close enough to have physical access to your radio signal.

We wanted to let you know what we were doing about it, and also what you should be doing about it yourself. Continue reading

Good news (for a change)

As a result of a long-term project accomplished earlier this week, subscribers are now seeing faster speeds and improved response times. Most subscribers are experiencing sustained speeds exceeding their contract limits (some are seeing double their contract limit), with an additional speed boost layered on top whenever possible for brief, non-sustained transactions such as web surfing.  Continue reading

251st Avenue tower outage Wednesday

Due to a recent real-estate transfer of the residence at which our 251st Avenue tower is located, we have been instructed to remove our tower.

We have already secured a commitment from a neighbor and long-time subscriber to assume the duties of neighborhood tower host, so we will be moving the tower to its new location during the day tomorrow (Wednesday). This will result in an outage of two to three hours for those subscribers and satellite towers served by 251st Avenue Tower, as the physical tower itself must be disconnected, detached, uprooted, transported, re-erected, cabled for power in its new location, and have its inter-tower feed links properly realigned.

After the relocation, we’ll be re-aiming the roof units of our closest-in subscribers first, then the farther-out subscribers as necessary. Our furthest-out subscribers in the vicinity of Circle City will likely require no re-aiming at all, though all signal levels will be compared before and after the relocation.

We apologize for this service interruption, and wish to assure you that we will be performing the relocation expeditiously, in order to resume service as promptly as possible.

Mockingbird recapped

I’m happy to report that, as far as we have been able to determine, all our speed-related problems at Mockingbird Tower are now resolved. Assuming this announcement doesn’t generate a spate of contrary responses, our next task will be to arrange for incremental UPS protection at our towers, beginning with the ones that are most highly subscribed; and working with our consultants to assure that we can deliver to our subscribers all the untapped bandwidth currently available at our Internet gateway.

For the technically curious, a brief description of the source of our speed problems appears below. (Warning: unpaved roads ahead!) Continue reading

Mockingbird improves…

We found and corrected the source of the frequent four-second timeout pauses. Mockingbird subscribers will now at least be seeing consistent data delivery, just not yet at the speeds we would like to deliver. What the tower is delivering right now should be fine for browsing, mail, and even a Netflix movie, but heavy data demands like Windows/Mac updates will still take longer than usual.

We are continuing to work on the speed problem with our dedicated and knowledgeable consultants.

“Big Sleep” to blanket Mockingbird tonight

After last night’s testing, we suspect the most probable cause of the performance problem at Mockingbird is a bad customer roof unit radio hashing our tower. We’ve exhausted all the minimally invasive tests we can run. Starting tonight, we’re running a Big Sleep test on all our Mockingbird subscriber units. Continue reading

Mockingbird Update

After several abortive ordering attempts (in which “in stock” on a website listing apparently translated to “let us check our warehouse” once the order was placed), we located a dealer with a replacement antenna actually in stock. We have been verbally assured that our replacement unit shipped yesterday, and are awaiting written confirmation including a tracking number. In the absence of nasty surprises, we plan to be replacing the Mockingbird central antenna this weekend.

We are also going to be subjecting the Rio Vista antenna (same manufacturer and model) to testing to determine if it shows any early symptoms of the same failure mode, in case a prophylactic replacement is indicated.

Mockingbird Improved

As of about an hour ago, we believe we have found our issue with Mockingbird Tower Central, and taken steps to provide immediate improvement. Although speeds are not at the level they were three weeks ago (due to suspected antenna hardware damage and pending part arrival and replacement), they should be greatly improved over the degraded performance seen over the past week. Please drop us an email if you are not seeing adequate performance for your equipment.

Technical details follow for the curious.
