Ubuntu 15.04 and Ralink rt61pci Problem

update 8/12:
The latest is I removed network-manager and use wicd to "manage" the network.  I think it's better than before but still iffy.  I know it sounds very not scientific but that's me because I am not scientific.  Basically the Wifi support for Ubuntu 15.04 has been terrible ... for me if not for everybody.  I think this article kind of resembles what I experience.  In the last post it says "removed network-manager package, and used netctl for managing wifi, and the problem is gone"  I am not wizard so I have a difficult time figuring how to install netctl in Ubuntu GNOME.  In the end I gave up and installed WICD.  At some point it got stuck at 1Mb/s but if I wasn't dreaming I think it did connect at 36Mb/s.  It now connects at 11Mb/s.  I am not exactly complaining as long as it is double digit.  All in all it's iffy.  Not good.
Before I did all the above I also ordered a card that supposedly works out of the box on 15.04, I will find out soon.  It's a b/g/n card with max rate at 300Mb/s.  I doubt I can reach that but I would be thoroughly thrilled if it reaches 50Mb/s, the top speed of the router.

I guess I was happy too soon.  The connection drops and wouldn't reconnect.  And when connected the rate drops to 1Mb/s, like modem or something.

I am counting on my new card now.
----------------

Basically I have very slow connection rate, from 1Mb/s to 11Mb/s or mostly no connection at all with this combination.  Prior to 15.04, 14.04 LTS or 14.10, the WiFi connection has been pretty stable and the quality has been satisfactory, I don't think I ever reach the 54Mb/s rate but at least I got some where at 20Mb/s.  (My WiFi connected MacBook Pro get more than 50Mb/s and noticeably faster)

I thought ndiswrapper would be the solution.  Alas it was, only momentarily.

So the struggle continues.

PS: I should have left it at 14.10 because seemingly the WiFi is solid and I have no random reboots like I have had on 14.04 LTS

PPS:  In addition to the WiFi problem, I have had a few random reboots in 15.04 already.

PPPS:  Shotwell unequivocally continues to suck.  Part of the library continues to disappear, the import is still very very problematic.  I wonder does anybody ever get it to work like normally?  Part of my motivation to get on board to 15.04 was to see if Shotwell would work better.  Now I know.

PPPPS: So in a nutshell, the 15.04 offers no benefits to me.

https://ubuntu-mate.community/t/solved-ralink-rt2561-rt61-wifi-problem-15-04-beta2/828/7  this is where I got the idea.  Unfortunately just like one of them, the ndiswrapper doesn't quite work for me, it drops connection just like the Linux driver installed originally.

2015 Kissena Twilight Series Week 14


This is done with pan.  The yield should be higher if only I remember to stay very focus, and just follow and predict where the movement is going to be.

Sunpak auto 120J

Every so often, I got myself into some photographic gear obsession.  My latest infatuation is the bare bulb flash from Sunpak from many many years ago.  I got one with a hair line crack which turns out a bit worse than I thought or led to believe on the listing.  Whenever I pivot the head, the casing moves and the crack actually expands.

So I got myself a little project.  I got myself some epoxy.  I could have just applied it on the crack.  But I thought it would be cool and more thorough to disassemble the flash to apply the epoxy.

I know I am not a handy kind of man when it comes, actually everything.  Still I go ahead.  Because I need to desk adventure or maybe I secretly wish I would screw up.  The moment I opened it was the moment I regretted it.  But I never learned.  I applied the epoxy when inhaling the toxic fume and got my fingers glued together.  Next time if there is a next time, I will wear gloves.  I waited for the following day before I put the casing back together.

A picture is worth a thousand words.  So here we go.  A bunch of iPhone pictures.

I only disassembled the base and mostly the top half.  Lucky that there wasn't any electronic part to fix.  But just to open it up and putting it back together is such an ordeal, for me, anyway.

I was pretty much sure I couldn't put it back together.  But lucky me.
















Well I hope the pictures will be of some help to some folks.  I did try to search on service manual or repair manual or any diagram or pictures but to no avail.  I dare not nor do I need to open the head.  So I guess the pictures won't be a lot of help.

Do it any your own risk.  You may get electrocuted by simply opening the case.

AirDrop

I wish AirDrop can work like 99% of the time.  As of now, AirDrop kind of works like maybe I don't know, when it feels like it.

After I processed my Instagram pictures, I just AirDrop it to my iPhone 5s so I can upload them accordingly.  I really like the Instagram way of doing thing.  They will only support desktop upload until hell freezes over.  I really admire the stubbornness if not anything else.

Back to AirDrop, it really works mysteriously--for ignorant people like myself almost anything works mysteriously.  Initially I thought AirDrop works with Wi Fi but I notice when I turn on AirDrop it also turns on Bluetooth.  So I have no idea.  I think it gives more trouble with iPhone 6--again it does work but with extreme temperament.  My experience is AirDrop works actually better with iPhone 5s.  I am talking about MacBook Pro with iPhone here.  Though I have heard some people claiming AirDrop is meant for iOS devices only.  To those people I'd like to say go to have fun with yourself.

Drive in Theater


About to watch Inside Out and the latest Terminator at the Warwick Drive-in Theater.

Barber Shop in Chinatown

 Nowadays I loathe to have my haircut, that's why I seldom have mine cut, maybe once or twice a year. I went back to Chinatown. I could ...
