Okie Kokie, I've got two pc's currenly hooked up with wireless, both laptops. Soon i'm going to get some wireless cards for the proper pcs in the house, and connect those too, but i'm loathed to do that if i have other issues with the wireless.

Now, the two laptops are as follows: Samsung R20 C2D (new) with on board wireless. and a old Sony Vaio Duron 1ghz machine. This requires either USB dongle or PCMCIA card wireless as it has no on board lan of any description. Sky sent us a Netgear 54mbps dongle. This was 'kin useless, so we contacted them, and they sent out an identical dongle, but 108mbps. The R20 is running Vista home premium, and the Vaio is running XP - probably xphome.

The router is a Netgear DG834G which came with the sky bb.

When we first got it, the wireless was absolutely useless. This R20 would connect wirelessly as long as you were 4 feet away or less. The Vaio with the dongle wouldn't connect unless you were 4 inches away from it. This is when sky agreed to send out a new router, but sent the 108mbps dongle instead :confused:

Before that got here, one day i just happened to notice while i was watching a movie up here (other side of the house to router) on the R20 my wireless suddenly started working! Yes! thought I. Got excellent signal too. This was for no apparent reason, the only thing i can think of is sky sent a firmware update to the router to fix this.

So i went to test the Vaio (still on 54mpbs dongle) and hey presto, that worked too, although not as well as my R20 - keeps dropping out even in the next room to the router.

We don't have thick walls, or any major interfering devices in here, however this lappy picks up several wireless networks that aren't ours, like our next door neighbour who has a rangemax router, and the ppl up the road who have a Billion router. - and another one who i dunno whos it is

I'm guessing that the new dongle, which is faster, won't get any better signal than the old one

So i'm thinking all's cool, send both dongles back to sky and get a refund, then get some of these belkin pcmcia cards with pci adaptors, one for the Vaio, two for the towers. - Haven't done this yet - prob tomorrow or fri

So just now i'm on the net on the R20 and suddenly, for about 5 min, even my wireless went down completely. The R20 still picked it up, but couldnt connect, and showed only the smallest bar of signal.
What was really odd was the other networks in the street i can pick up, were still getting really good signal strength... Then it connected but with v.little signal.. now its back to full strength again? Weird. Why would it suddenly drop out then suddeny work again?

I'm going to try the other dongle in the Vaio and see how that is, if it isnt at least as good as this R20, it'll be PCMCIA networking, all the way.

Thing is i'm fairly new to this wireless stuff... The Belkin cards are 54mbps but have MIMO extended range. Our router and this R20 are 54mbps, non-MIMO.

What effects will putting 3 of these cards into our network give? Will it all still work, including my R20? will the mimo cards connect to the non-mimo router? Will they in fact boost our network coverage? (seems to me they should)

And how come the PCMCIA Mimo cards have no antenna whatsoever.. one would have thought an extended reach would mean greater antenna equipment.. :confused:

Have you tried using a different channel?

If you are on the same channel as one of the other nearby wireless routers that would go a long way towards explaining your problems.

The MIMO cards would only be of any benefit with a MIMO router and although they should connect to your current router they may in fact deliver a worse performance as your router has no facilities to support their MIMO capabilities.
 
isnt it all a case of bananas is bananas?

I mean, the frequency/protocols should be the same.. Not bothered if i only get the same performance as a normal card, but if MIMO makes it worse... the VAIO wont be able to connect.... Thing is all the other PCMCIA cards are like £40 even for a non-mimo one.. this one is £15.

is all so confuzin.. and of course the companies will tell you you need a new router, as they want to sell you one :mad:
 
There seems to be lots people posting wireless problems with the Netgear 54mbps DG834G router....
(my sister has this DG834G router and have had problems with the wireless range,her daughter laptop will only pickup the wireless signal if she in the same room as the router,but her son laptop will pick it up all around the house,there both the same laptop models :confused: )

I used to own the 108mbps DG834GT one and i never had any problems with using the wireless all around the house and in the back garden with great signal strength....My mate next was even using it for internet access for a few months before he moved..

You said yourself that the MIMO cards had no external antenna but they will have two internal ones and they will depend on using the multi-frequency MIMO signal with those two antenna.

Without a MIMO router those cards are going to have a harder time and if the signal strength is poor even when you use cards that do have an antenna then I can't see the MIMO cards making things better unless you use a MIMO router.
 
mine's a DG834GT too, the 108mbps one.

actually the wireless is working pretty much fine now, have changed the channel and it's fine.

I actually dont use any cards with ext antennas at the mo - just a usb dongle on the other lappy and my lappy's on board wireless.

The proper pcs i am connecting wirelessly, i've used both laptops next to them and they seem to work there.

My confusion comes from this:

Will the card being MIMO hurt its performance, Will it actually be worse than my laptop's on board or that USB dongle? :confused:

EDIT: those cards are £15. I can get USB 54mbps dongles for £8. I'm loathed to do that cuz i know they take 'puter power to run... hmm.. might be worth trying my desktops with the dongle we have... I just brought the lappy with the Netgear 108mbps dongle we have up here and put it where the other pc is... "low" signal - it still worked but wasn't very good. i think that might be the limit of USB devices... Would a PCMCIA MIMO be better or worse? anyone know?

This is a classic case of a little bit of knowledge being a dangerous thing.. i have a little knowledge, i know what absolute ****s computers can be, this means i know enough to raise these questions but not be able to answer em, as i'm fairly inexperienced with wireless (currently setting up my first wireless network ever) - sorry you guys but i am a n00b when it comes to this stuff.. ask me about overclocking a 32bit athlon or early intel chip though... lol :D

EDIT2: can't wait to rebuild my wired network.. at least i know that stuff.. gots ta love RJ45/CAT5.. should be fun making a hybrid wired/wireless network, with a router to share the net across the house sat downstairs, and link downstairs to upstairs, and a 5port wired switch upstairs to handle file transfers and linking the upstairs pcs - we can't run any cables up-to-downstairs :(
