I just sorted out a very geeky problem I’ve been having, and I’m feeling pretty proud of myself. Prior to coming to Korea, I ordered myself an Asus EeePC 901. For the most part, it’s been a fantastic machine. My one complaint has been the wireless performance. It’s mostly OK at my apartment, but on the go it has a real hard time connecting to access points. If the signal strength is anything less than stellar, it’s just pretty flakey. It may be a linux-related driver issue; I’m not sure.
Regardless, I’d had enough, so I ordered an Intel 4965 AGN card prior to my parents’ visit. The original Ralink card used 2 antennas. The new Intel card had jacks for three. I’m pretty sure that three antennas are required for true 802.11N speed, but I haven’t done a lot of research on it. Something about MIMO (multiple input/multiple output) support. I thought 3 was probably better than 2, so I spent $5 and ordered one. I don’t use N networks now, but I figured I might in the future.
Ideally, I would have disassembled the machine and found a good location to stash the new antenna, but the wire was really short, and I didn’t want tear everything apart. I just stuck it under the (shielded) access panel. I knew this was a piss-poor location, but I figured that I wasn’t using wireless N anyways, so it probably didn’t matter.
I made this update right before going to Thailand. Everything seemed to be working well. The new card connected to networks faster than the stock card, battery life was better, and it seemed to do a better job with weak signals. I didn’t do a lot of testing, however.
I only used wireless a few times in Thailand, but things didn’t go well. The connection was laggy, and Skype had terrible delay or dropped calls. I blamed it lack of bandwidth, but the problems didn’t go away when I got home. Even on my (excellent) Korean connection, I had problems using Skype.
Tonight I tackled the problem. Ping showed terribly inconsistent latencies, and tons of duplicate packets. At first I blamed my crappy router, but my other laptop had no problems. Traceroute didn’t help narrow down the source of the problem.
I pulled the new wireless card and re-inserted the old card. Problem solved. This had me really frustrated, because the Intel card is pretty much brand new. I tried the Intel card again, but without the third antenna. Bingo! Low latencies and no dropped/duplicate packets.
I don’t know enough about the hardware or the wireless N specification to really understand this one, but it appears that the case shielding was messing up the third antenna, which caused the problems. I’ll watch it for a few days, but the problem seems resolved.
I love easy fixes. I suppose the moral is to do things right the first time, but methodical troubleshooting is critical when problems arise.
We’re back from Thailand. It was a great trip, and I have tons of pictures and lots to talk about. Look for updates soon. Also, we had a great time in Korea with my parents. Again, pictures and updates to come.
I hate to rant on my first post back, but there’s something I have to get off my chest. I hate dinner meetings.
Here’s the background: We got back to Gangneung on Friday and had to go to school on Monday. No classes, so we’re sitting at our desks and planning. We’re told sometime in the morning that we have a dinner meeting for the teachers that are moving to new schools. As far as I can gather, this happens about every semester. Teachers have to go to a new school at least every five years, to avoid stagnation and corruption, I guess.
Dinner meetings are pretty common; we have them for all sorts of reasons. This is maybe the 6th or 7th such meeting that we’ve had thus far. Here’s the scenario: Erin and I catch a cab to the beach. We sit down in a big room with all of the teachers from school, maybe 50 total. There’s no formal order to seating, but all the women sit on one side, and the men on the other. (Side note #1: the male teachers at school speak very little English and tend to ignore me.) I have the option of sitting awkwardly with the men, or sitting awkwardly with the women. I opt for the women, because I can sit with Erin, and because they speak English. I side as close too the men’s table as possible though. Regardless, this seems to be some sort of testosterone-related faux pas. Nobody wants to talk to me.
Side dishes come, then raw fish. (Side note #2: I can’t stand raw fish.) At some point, soju is brought out. The drinking begins. The men start drinking heavily, or at least pretending to. Same with the women. They pour water into shot glasses if they don’t want to drink soju. After a few drinks, both the women and the men are getting red-faced and giggly. I’m sitting awkwardly at a table.
A few more drinks, and the third course is served. Some kind of fish soup. Soju is still flowing. At this point, I get flagged over to a different table, where Erin is pounding beers with some of the younger female teachers. I join in, because company is nice. We have a couple drinks, but my head really isn’t in it.
Then the real fun starts. My co-teacher is one of the older male teachers, and seems to be the de-facto MC. He stands up and starts asking teachers to sing. Last time this happened, Erin and I got called up and performed a horrendous rendition of “For He’s a Jolly Good Fellow” for the teachers that were leaving. Thankfully, we were not called on. It should be noted that I have a terrible voice. I’d prefer not to demonstrate that fact publicly. I’m also not much of a drinker. Even if I were, no amount of rot-gut soju could make public singing a comfortable experience. NOT being called up was the best part of the evening.
After 20 or 30 minutes of singing, the group decides to move on…to a norebang. This translates to “singing room.” You guessed it…more singing! (A norebang is a building full of little rooms with screens and kareokee machines. Drinks and food are often served. It’s part of Korean culture that I do not understand at all.) At this point, Erin and I made our excuses and left with another teacher. Thankfully, this didn’t seem to be TOO much of a big deal.
As I’ve made clear, I really hate these meetings. It was better last semester, because one of the temp English teachers was a male who spoke excellent English. He made the whole situation a lot easier. It’s frustrating for me, because I’m pretty sure that if I drank a half-gallon of soju and generally acted foolish, I’d fit in much better. I’m certainly not saying that every teacher does this, but plenty do, and it drinking is a pretty big part of male bonding in Korea. It’s just really not my style.
Enough of my whining. We were able to escape the meeting after 2 and a half hours, which isn’t too bad. At least we avoided the norebang.
I’ve been even lazier than usual with this blog, but here’s a quick update:
- School camps ended Friday, January 23. They were reasonably successful
- My parents arrived in Korea the same day. We spent about 10 days traveling. Everything went really smoothly. We saw Seoul, Gyeongju, and Gangneung. Pictures will be up later.
- Erin and I are currently waiting in Incheon International Airport. We’re about to fly to Thailand for 17 days of vacation. If you currently live someplace cold, enjoy this weather forecast.
That’s all for now. (Erin is kicking me off MY computer.)
