SL rebooting wi-fi connection when logging in

Just wondering whether anyone else is experiencing the following issue and whether a solution is known.

Downloaded the most recent update of SL on 13th November 2007. Since installation, whenever i log onto SL, my wi-fi router reboots itself and i crash before I have loaded. Consequently, I am having to use a cable connection to access SL, as opposed to wi-fi, and I am crashing all of the time, or freezing, for no apparent reason. I could be looking in inventory, TP-ing somewhere or just chatting, there seems to be no regular reason for the freezing/crashing.

Is anyone else having issues with wi-fi connection? I know this update has created multiple crashes for lots of people, but I am mystified as to why it is rebooting my wi-fi.

LL have yet to respond.

regards

a very frustrated Flicka B.

I do not think too many others are experiencing your particular problem... The SL FAQ clearly states that wireless connectivity used anywhere between you and SL is not recommended. The very nature of the service and how it utilizes the network stream makes Wi-Fi pitch fits.

I tried with multi-channel bonded Cisco 802.11A and even proprietary 802.11G radios in speed in excess of 100mb/Sec transfer rate (we all know that this is a made up theoretical maximum) and still experienced trouble from login errors to stalls and stutters in-world once there. Rezzing was slower too, though the radios out-performed link-wise my broadband connection.

Wireless and SL just doesn't work well or as stably as one believes it would. Ditch the radio and plug in your copper line.

EDIT: Another possibility is that your wireless router over-runs it's internal route/MAC tables with the sheer number of requests/transactions taking place when logging in and first rezzing in-world until things calm down and are cached. Some routers cannot handle more than 30 simultaneous connections, inbound or otherwise and drop routes/reboot. I had a D-Link famous for this until I replaced it with something else.

I don't have any trouble using a Wi-fi router on my Mac. I have the built-in "Airport" 802.11g card and use Belkin wireless ADSL router to connect to the internet.

My previous set-up was to use an Airport Express base-station (802.11g wireless router) which plugged into an ethernet router which then plugged into a cable-modem and it ran even better than the current one. My main issue seems to be with my current, crappy ADSL internet connection.

I'm glad it's only for another five weeks then I'm moving back to my previous set-up =)

Yeah, the radio in Macintoshes are based on a great product that I have managed to get my hand on without the Macintosh name on it. Turns out to be a great radio and AP set (Same guts as an Airport, again without the shape and name branded on it from Macintosh) but still suffered from occasional spikes in lag as the packet loss meter spiked. The radios were re-negotiating and skipping about in frequencies because I have neighbors that cannot be bothered to do a site survey. (Auto frequency hopping is the awesome, but makes communications pause if they are intensive like how SL does its thing)

So your environment would be more conducive to a better overall experience if you actually have airspace to lock to one frequency rather than struggle to shout over a flooded Wi-FI environment. Maxing the card and AP's output power made them "SHOUT" to one another and clarify the link, but these are high power 200mW radios where most consumer goods are neutered down to 30 or so.

So no doubt, I do not doubt you had a great experience, betting on the fact that the Macintosh products are solid performers. They have a reserve of power that they auto negotiate to overcome issues in the environment. Mine, they were spotty, hit and miss until power was upped all around manually. Chances are, the fellow that originally posted is dealing with rather common off the shelf stuff or worse, MIMO 802.11N junk that is pre-draft and doesn't even work with its own made-for-compatibility products from the same manufacturer. I have yet to see an "N" device that did not self-reboot every half hour like clockwork from *any* manufacturer. Wait for the IEEE to put a standard on it people! *giggle*

I used to have a problem sort of like this back when the first public voice beta came out. After staying in SL for about 10-30 minutes my router would freeze and I'd have to manually unplug and reset it. The issue lasted for about 3 beta versions and then mysteriously disappeared and I haven't seen it since.

(Note: This wasn't on wi-fi though.)

Spot on Bodie, after having so many problems with so called big brands of the WiFi industry and banging my head against the wall becuse they simply cannot perform, I popped on an Airport Extreme as an access point, I don't have any Mac's at all, but the performance and the stability of the connection is wonderful.

I usually don't use SL over wireless but I did test it and found it was more than enough to do whatever I needed. So go get yourself a little Airport Express my friend. Or perhaps Bodie can tell us what this mysterious brand that does not have the half eaten apple on it, would love to know.

i always thought they said wireless internet, not loacal area wifi, and theres nothing special about SL, its tcp/ip if they are doing something funny it wouldnt work over the internet, its just traffic

I tried with multi-channel bonded Cisco 802.11A
a 1mbs network connection, outdated 7 years ago

and even proprietary 802.11G radios
dunno whats so special about yours, they are commonplace

From: Bodie Bosch

in speed in excess of 100mb/Sec transfer rate (we all know that this is a made up theoretical maximum)
thats becuase you made it up, it nails 54mbs max (the limit of the radio) as long as you have over 40% signal strength

From: Bodie Bosch

and still experienced trouble from login errors to stalls and stutters in-world once there. Rezzing was slower too, though the radios out-performed link-wise my broadband connection.
well over your 1mb network DUH, and for your g mode it all depends on signal strength

ive been using g mode for almost 3 years with a 40+ signal strength with absolutely no issues, AND its actually faster, yes by the time i snaked unshielded utp around walls over doors and tru closets for almost 40ft of wire, the wire had so much twist in it that i could not get any faster than 10mbs, with moderate latency, so now do i tear out my walls and run shielded wire, or use a perfectly good wireless 802.11g (and got a free network card to boot)

Very helpful post there Osgeld. There is ahuge difference between different wilreless devices. After having thrown out so many, I should know.

Besides there is 108 Mbit wifi and has been around for over a year, check out Netgear's Super-G range for example:

http://www.netgear.com/Products/RoutersandGateways/SuperGWirelessRouters.aspx

So 54 Mbits is not the limit..

Seems like you are knowledgable on networking but trying to be superiour to someone else that's trying to help is not the reason why this forum is here. I have not seen anything that shows you wish to help this person, who's in need of help obviously. There are plenty of dodgy wireless gadgets out there, I had just returned a netgear adapter that refuses to maintain a connection yesterday, brand new and it is not faulty it's just badly built, it will establish connection and lose it within seconds trying to re-negotiate. Even the biggest brands make crappy cheap stuff and sell it for much more than others' that are better because they have a name. Dlink for example is one of the worst in my honest opinion and will never ever touch a D-link gadget in my life.
