Hey folks,
I enabled the "garden gnome" on the production exit server. What this
should do is trigger certain operating system's network connectivity probes
so that they'll show a splash page when people join the network. It's
designed to be as minimally intrusive as possible, so it only captures
probes to the specific urls that OSX/iOS/Android/Windows test to see if
they're connected to the internet.
Once a user clicks "go to the internet", that IP will be added to a white
list so they won't see the splash page again for 24 hours.
Please please please let me know if there are any issues that you
encounter. We absolutely don't want to have people unable to connect to the
network for some reason or another. I don't really have enough devices to
test on, so it's very possible that there could be an issue somewhere.
There are a couple design bits that I know I need to polish, but I'm open
to constructive feedback on any aspect of it.
Thanks!

Hi!
Interesting.
Maybe there will be some online materials.

EE 290 Q Understanding and Improving the Performance of Wireless Networks
Spring 2016, First class January 27th,
Instructor: Adam Wolisz
Time and Place: We 2- 4.30 pm 531 Cory
=====================================
Brief Description
Wireless networks dominate the "last hop" over which individual device
are connected.
The rapidly growing wireless traffic has a highly heterogeneous nature,
ranging from
massive video to highly delay sensitive real- time control data.In order
to assure the
required "quality of user experience" heterogeneous networks concepts:
e.g. cellular,
WLANs, sensor networks, delay tolerant networksare increasingly
considered not only
as alternative solutions but as parts of consistent heterogeneous
communication infrastructure.
This seminar will include discussion of methods and models used for
performance evaluation
of wireless networks butthe main focus will be on lessons which can be
learned outof the
performance studies: trends in networks design,opportunities for
improving the efficiency
of their operation, possibilities for harmonization of applications
and underlying networks.
Students are expected to have some familiarity with computer networks
and wireless
communication, be active in reading, presenting and discussing papers
as well as active
within the project work.

Hi all,
I'm one of people who started www.meshpoint.me - idea is to build open
source wifi router that can be easily deployed in any type of crisis
situations.
I have been setting up wifi networks in crisis situations and I know
that there are no devices that are usable in crisis situations.
Belive it or not but first responders usually aren't network admins :)
So that is why we started developing MeshPoint, wifi device that
anybody can use in crisis situation.
First iteration will use off the shelf components and later we plan
develop our own wifi router board using atheros hardware.
Our current design (as you can see on the web site) uses three TP-LINK
WR842ND (AR9341) boards in 3D printed case.
Our concern is that this could generate too much interference and
cause too much L2 retransmissions because of co-channel interference.
We are using latest OpenWrt 15.04 Chaos Chalmer and ath9k driver and
would like to know if it is possible to extract metrics that shows
number or L2 retransmissions.
Do mac80211 or ath9k tracks L2 retransmission statistics?
How can we get those metrics if they do?
>From my research up to 5-10% of L2 retransmission is just fine, but
anything over that is cause for great concern.
Is there any other metric that you would suggest we track that would
show some issues due to wifi interference?
Is there anyway to get AR9341 datasheet?
Cheers,
Valent.
I am in california briefly (for a conference) but have time free after thursday.

Let's go make home routers and wifi faster! With better software!

Hey folks,
There's gonna be an hour or so of network downtime tonight. I just got an email from digital ocean saying that we've received too many dmca complaints and that they're gonna bring down our server until I respond to the latest one. I'm out of the house for the next hour and I don't know that I can deal with it until I get back.
Sorry about this - I'm gonna try to get this fixed asap and avoid this moving into the future.
Thanks,
Max
Hi!

Hi all,
I'm writing comparison matrix between different outdoor wifi routers,
any comments or suggestion are welcome:
https://docs.google.com/spreadsheets/d/1TAqBaqCuS1vMnrpGoVNim9LVQfVovkr60fg…
Would you add some feature? Remove some? Add some device you believe
should be on this list? Are prices correct?
Cheers,
Valent.
