NUIG wireless

Simpleton

Maybe a stupid question. Wireless in around campus seems to be very variable.
Is there hotspots that are quicker than others?
I was in Áras Uí Chathail today and found really quick wifi.

Thanks in advance

Might just be the time of day and amount of people on the network, usually when I'm in the library on weekday afternoons it drops off regularly, but would be ok at the weekend.

library 2nd floor and reading room have crap wifi during the week.
the IT building has the best wifi. aras de brun has fast wifi too (probably cos no-one's ever on it ) the concourse has variable wifi during the day but it picks up in the evening.

No problems with the GMIT wireless.

Bingo.

It's a shared resource. For 802.11g, it's 54Megabits/sec raw (Physical PHY layer) shared between every connected client's downstream and upstream connection.
That's before you take into consideration all the other layers of network gubbins (overhead) that ride ontop of that combined with 2.4Ghz interference from all sorts of stuff (ie. people) and the nature of an omni-directional open-air transmission medium.
It really really doesn't handle more than a few dozen users well.

If you want speed, jump on a lab workstation with a nice fat wired connection.

Concourse and library is crap. IT building is best rigged for Wi-Fi. For example:

commerce building is the best i find

I always find the Cairnes building to be the fastest, especially around exam time. If you bring an ethernet cable with you it's even faster.

The lib has its good days and bad days...today being a bad one less then 0.26MB on download all thats missing is a dial tone. that's what I get for going up to the third floor!

On the middle floor of the library. Took me 10 minutes to download a 3.6 mb file from blackboard.

At least it encourages us to stick to the books than "researching" on the net! :P

Wikipedia has got me this far anyway!

Would adding more wifi access points around the various heavily congested areas alleviate the problems people are encountering?

What you can plug into wall jacks in college? I thought these would be secured by mac address on the switches , i.e. you would have to have a registered PC, not a student laptop, to use a wall jack.

Also the people who are using speedtest.net images, I doubt you would ever achieve those speeds on wifi in the college. I would imagine that there is a speed limit imposed on each client through the college proxy/firewall.

po0k you seem knowledgeable on this subject perhaps you could enlighten us please

Through the wired network in the IT Building :cool:

*Ahem*




I've rarely used wifi outside of the IT building, have never had a problem. At least it's better than a few years ago when a certain 'project' site was very popular.

brianthebard

Lol in fairness I imagine there are a lot less people using the wireless today and yesterday than there was when cosmicfrog and I posted. Still I wouldn't have thought there could be such a disparity in speed.

toiletduck

Oh, my speedtest wasn't from wireless. I was just out e-penising KevR's wired IT connection :pac:

KevR

@ Brian, my speed result was from a few weeks ago when there would have been normal attendence at college. I posted that result in a different thread on boards a few weeks back and was at home when making that post yesterday so just copied my result from before.

The speeds you got are awesome!

Lol. I did see you had a different isp. Was it in college somewhere though? Be interested in hooking my laptop up to something like that some night.

toiletduck

It is in college yeah, but not available to any Joe Soap. You'll have to take my masters place first!

F.Galway

Well it beats the third of the library anyways! maybe one day for the library.... :P

Did you connect to the wired network through your laptop, or from a PC?

RolandIRL

from the physics comp suite, which is now full, so maybe a bit slow.

That was through a PC. Have never tried connecting my laptop into the wired network, not sure if it can be done or not..
