what are you doing actually? the signal drop depends on your distance with the router, as well as the antenna used(internal or external, for your case would be internal).

are you doing anything network related all the time? probably the raspberry pi is saving power on the usb wifi dongle perhaps?

but still, there's nothing with it though.

At the terminal:

1. iwconfig

2. nano /etc/network/interfaces
3. add "wireless-power off" after any wlan0 lines

i.e

auto wlan0
wireless-power off

4. reboot
5. iwconfig and you will see that your power management is now off.

Reason Code 8: Operating System moved the client to another access point using non-aggressive load balancing.

You can try the workaround at here, but I'm sure whether it will work for your case or not.

Anyway, try to replace your power supply to a better source and use a better cable(better quality and shorter would be better)

you must be good then

nobody want to hire me as part time tutor

If you don't want to go for the hardware side,
1. ftp + web server + torrent
2. xbmc

would be a pretty practical usage for the masses

If you want a "wow factor" then most likely it would be some hardware hacks

true that, was using raspi as a download server but in the end changed to my old desktop because of the 100mbps ethernet and limited storage.

........

what's your targeted users? IT students? general masses?

and please, as for any hands on workshop, please ensure that you have a fast internet for all, or else the whole workshop will be a mess(seen and taken a lot of workshops like that)

Not particularly sure about whether there's a script for dyndns but there should be though since dyndns is pretty popular. I'm using ddclient with cloudflare instead.

For public access, just access it via the fqdn that they gave you(usually is ur specified subdomain + the domain that u chosen). But if you're using streamyx <1mbps or any mobile broadband solution then it won't work because they are using private ip.

then............ a bit of modification
1. ftp + web server + torrent(set up web ui) + samba + minidlna + securing it + port forwarding + dyndns
2. xbmc

xbmc is pretty straightforward actually........ so I think the 1st one would be better as it would take more time and it would be a bit harder to do

dd? should be able to do the job although I have yet to try it

yeap. that way would be easier but I'm pretty skeptical of those ddns setup anyway. Back to topic, you would go for the internal network setup instead as you would be getting a private ip instead of a public ip. btw, you may want to go to the uni to test things out a few days before the talk because they may block some of the ports that you may need

not really, you can use the free subdomain that dyndns provides. I used my own domain at cloudflare because I have some in spare. but still, I haven't used dyndns and noip for quite a while already(at least 5 years back?) so it may be a bit outdated.

Samba is a file sharing protocol, and Windows has built in support for it natively(so it is easier than ftp in terms of setup in a sense, but ftp has been around for quite a while so if he/she has been working for a large company then he/she should be more familiar with ftp instead).

yeap. setup wise a bit tedious but at least it is just a one time setup and easier to use imo. anyway, its your call.

I did mentioned the answer at the last line though, which is dd. Here's a link on how to do it: http://raspberrypi.stackexchange.com/quest...my-raspberry-pi

nah, me too, still a long way to go

if you still cannot find the solution 2 months later, bump me and I'll see what I can do because I didn't have my usb webcam with me for now

I believe this is due to the additional RAM. SQL query speed are pretty much dependent on the amount of RAM available on the system(whether you can fit everything into the RAM)

Not particularly sure without having access to your resources(sql query, pi and pi2 setup, and etc). It depends on how big is your db though, I don't think you'll be running a medium sized db at pi2 though

Not sure what with my raspberry pi nowadays......... since I've repurposed my old computer to become the download server and webscraper instead

how large is your db at the moment?

I think you can go more than that with rpi2 as the review that you see was done with rpi model b. My rpi model B typically maxes out at around 8-9mBps with the built in 100 base T adapter(although, don't think too much because your sd card will be a bottleneck once you go over 100 mbps)

Nope, it would be dependent on the speed of your hdd(which would be more than enough). Nope, it was just a blog that I found while googling.

Banana pi is faster because it uses a dedicated chip for the gigabit nic and usb 2.0. So there's no bus sharing resulting in loss of performance unlike all rpi generations where the usb 2.0 bus is shared by all usb devices and the internal nic. Not to mention that the banana pi has a powerful cpu compared to rpi(not particularly sure against rpi2 because I have not checked on that part).

p/s: to be honest, if you wanted to do file sharing via samba/nfs, may as well as get banana pi or banana pro instead

what are you doing with them?

you don't really need bleeding edge updates though, although device support is important(like to support the IR receiver that you're using).

just leave it on. I have 3 rpi + 1 desktop running 24/7 at my room

it depends on their next soc actually, because processor, ram, usb is built into the soc so we will just have to wait until the prices of more powerful soc becomes more affordable
