Wireless connectivity issues (input needed)

Have you tried to crack it open and plug in the aux antena? That did wonders for me.

This is really odd, I have had no problems whatsoever...
Hope you can figure it out!

First of all:
Why didn't you post this on the tech forum area? Since you are one of the people who post there and look for information there, you should know better that this kind of useful discussion should stay there.

Now, on more useful information:
I have some problems with wireless too. Not only it drops the connection every once in a while, but often it doesn't get any signal when other computers in the same place would be getting a weak or medium signal, and often it connects but doesn't send/receive any data.
I have also faced problems with a Dlink wireless router. It would connect, get an IP address, have an "excellent" signal (I was 3 meters from the router) but it wouldn't receive any packets.
I haven't done extensive tests (especially because I don't have time and I don't use wireless that much), but the info I can add is:

The problem is not the wireless card itself. I concluded from this: I placed the 5720 and a 8790 in the same table, at the same (large) distance from the wireless router. With the SAME set of drivers, while the 8790 would get a 'medium' signal, the 5720 go NOT SIGNAL AT ALL, even with A disable and set to maximum performance. To avoid one computer interfering with each other, when one was turned on, the other was turned off during the test.

Then I exchanged the wireless cards on both laptops. The result was exactly the same: 8790 with medium signal, 5720 with no signal.

I also tried to plug the antenna cable that is connected to my bluetooth module to the wireless card, but it didn't help AT ALL.
I also tried changing the PCI slot, but didn't help (and I couldn't disable it with Fn+F11)

In a few older threads, people mentioned changing the intel card for an atheros card and getting wonderful results. That makes me wonder if the problem isn't some compatibility issue between the 5720 mobo and the board or something like that, which then makes me wonder why would Intel give Clevo the "Centrino" sticker if the wireless card didn't work with that mobo...


I have to agree with your complain in other thread: it is pathetic that such a machine can't have its wireless to work properly...

Do you use the wireless often? When you do, are you located nearby the access point??
It would be interesting if we could compare and see if there is any difference between our systems that could be causing these problems.

At home, I am right next to my wireless router. To tell you the truth at home I usually just hooked up the lan cable so I can transfer faster on the network. But, I use it all the time at my college, and the wireless points are all spread throughout the campus. I have used it in several areas with no problems at all.

Theres three antenas inside the 5720 and 5320. One for bluetooth, and the primary and aux antenas for the 802.11. Sager does not hook up the aux.

On mine there are only TWO antennas: one for bluetooth, one for Wireless. The third cable goes to the tv tuner "antenna IN" in the back.

The little wire for the TV tuner looks like the wires for the wireless antenas then. Sorry

Kumaiti is correct there are only 2 wireless antennas. One for WiFi the other for bluetooth. The third is the TV antenna for the TV tuner which is installed in my 5720. I do not have bluetooth and my aux antenna was disconnected.
I have done the following:
Connected aux lead. - helped a little but would still disconnect.
adjusted power management setting and installed latest Intel Pro wireless driver while still letting Windows manage connection - Would still disconnect.
Let the Intel utility take over wireless duties while making sure the power management settings were where I wanted them. - No more disconnects
Never wanting to leave well enough alone I read about some Alienware folk using Atheros WiFi cards in their laptops - purchased a Atheros card with the 5002 chipset and Installed the Client that came with the card. Wow major difference, Signal is stronger, better ping times in games, basically better all around.

The gray one.

Wow total bashing of the sager wireless and i've had not one problem with mine. at my home the router is next to me i can connect to that without no problems, Theres people that have unsecure wireless around here with 2 bars and i can connect to those without problems, It sounds like a problem with your router maybe you need a better one? How many bars do you get? As for other people having the same problem alot of people don't know what their doing when it comes to hooking up a router lol.

Unfortunately the only solution that worked for me involving the disconnect problem was letting the Intel utility take over.

I am like BattleRoyale, I can see like 15 or more other wireless connections and connect to the unsecured ones that even have only 1 bar.
I do not get disonnected either. I have used just wireless to bit-torrent, download regularly (large files), transfer stuff over my network and play games.
The only thing I have noticed is that in Call of Duty depending on the server I sometimes get a split second lag spike, but I am not totally sure this is because of the wireless.
I overall have not had any issues with the wireless. At school it works perfectly and at home. Even at my uncle's house a few months ago I used his wireless and it was great. My friend in Japan has a 5720 and he uses wireless and he has reported no problems either.
I know the routers I use are all lynksys. I have also used a netgear router without any troubles too.

I've also done all those things and the only routers i have connected to were netgear and linksys ones, maybe theres problems with crappy brand routers.

I am actually downloading at 200kbs on bit torrent and browsing this forum just fine
