About Intel WiFi Link 5300 AGN

Hi everyon! Happy New Year.

 

I received a new T400s at last week.

OS is Windows 7 and my wireless LAN card is Intel WiFi Link 5300 AGN.

 

It doesen't works well.

It happens to disconnect network 5 ~ 10 minutes interval.

 

I have two another notebook.

They have no problems.

 

What is the problem?

What do I do?

Re: About Intel WiFi Link 5300 AGN

I'm having the same problem with my T500 (same wireless adapter, Intel 5300 AGN) since upgrading from Vista Business to Win 7 Professional.  I had no problems with wireless connectivity under Vista.  From what I can tell, this seems to be a problem with the 5300 adapter running under Win 7 on the T400/500 platforms.  I've tried everything, and I haven't been able to find a resolution on this forum up to this point.  I believe this is a problem Lenovo owes its customers a solution for.

I had the same problem and this fixed it for me.

 

Go to Control Panel, System, Hardware, Device Manager, click on Network Adapters, then click on Intel WiFi Link 5300 AGN.  In the Property screen, choose Power Management, deselect default value and move the slider all the way to the right (marked highest).  Ok it.

 

Hope this helps.

I have a new T400s with this card as well. Had it for 4 days and not one drop out. Hope you get it sorted.

What also helped in my case ( same WiFi adapter).... was updating the firmware on the router.

Re: About Intel WiFi Link 5300 AGN

I bought a T500 with intel wifi 5300 agn a few days ago and also found this problem. fortunately, I fixed it yesterday. You guys may try my solution.

 

1. open control panel and then open device manager.

 

2.open the properties of the intel(R) wifi link 5300 AGN listed in the device manager

 

3.select the advanced, disable the 802.11n mode and then save 

 

If you can fix it using this method, your prombem is not due to intel wifi 5300 agn card, not the drives, not the window7,  but your router. You should buy a new router supporting the newest 802.11n.

Well, i think its called 5300 AGN because it should automatically detect the A-standard (11 Mbit/s), G-standard (54 Mbit/s) or the new  N-standard (>160 Mbit/s), whichever is available. So if you have a G-router it shoud work. Period. No need to let everybody buy a new expensive N-router, at least not for this reason. If you have G and the laptop wifi doesn't work correctly, where it does on other laptops, then it's a Lenovo problem. If it works with N and not with G, it's still a Lenovo problem.

In practice it is usually a router firmware issue.  The Intel cards are very widely used right across the laptop brand spectrum  and the reported issues with them almost always resolve to router related problems.

 

It is sad fact that many WiFi router providers cut corners on the implementation of the various iterations of the IEEE 802.11 standards. and get caught out when a later enhancement to the 802.11 standards group relies on a cpability that was always specified but they had not bothered to implement.

 

In the case of 802.11n, there are many routers which are sold as 802.11n, but do not implement 5GHz WiFi support and will not work reliably with devices which are implemented to the 802.11 Draft 2 (and later) specifications regarding the use of bonded channels in the 2.4GHz band.  The Intel "N" laptop cards are all 802.11n Draft 2 compliant.

 

Cheers,

 

Bill

Hmm, about the 5G is interesting yes. So the modem negotiates N-standard where one side tries to operate in 2.4 GHz band where the other side tries the same in the 5 GHz band.  So sh*t happens with mixed draft 1 / draft 2 standards. So it depends upon the fact that one of the channels in the bundle, chosen by the draft 1 router, is the 5 GHz band to make the draft 2 wifi adaptor work (at less speed when some channels are in 2.4). That sucks ;-)

 

Thanks, Jan

Re: About Intel WiFi Link 5300 AGN

I'm using a Linksys WRT600N dual band router (2.4/5 GHz). By default, Linksys have set two different SSID names for 2.4 and 5.0. If the same SSID is set for both.... the speed doubles in theory. However, in reality it causes a slowdown due to interference.
