Zdravim, potřebuji poradiť. Kdysi jsme měl v notebooku FSC ESPRIMO Mobile V5505 (OS Win7 x64) síťovou kartu WiFi Intel® PRO/Wireless 3945ABG (802.11a/b/g).
Ta byla vyměněna za Intel® Wireless WiFi Link 4965AGN (802.11a/b/g/n).
Problém je v tom že k WiFi Routeru TP-Link Tl-WR 1043ND se mi připojuje vždy jen rychlosti max 130Mbs...
Může byt chyba v tom že, notebook na tu N kovou síťovku nebyl nějak uspusobený??? :confused:
Nebo je chyba jinde???

Myslím si, že toto je asi dostatečně výmluvné:

Duration of ownership: 2 Weeks
Strengths: easy installation, good signal strength and pick-up range. faster than wireless G
Weaknesses:somewhat unstable. not as fast as advertized.
Overall Evaluation: I upgraded the wifi card of my dell m1210 from 3945abg to this 4965agn. I'm using it with a Netgear WNR854T which has been certificated by Intel for the "NEXT N" compatibility. First of all, check the compatibility of this card with your laptop and your router. This is an "express mini pci" card which works only with the Santa Rosa chipset (centrino duo or pro) as long as I know. And currently there is no market-wise standard for wireless N. Intel's Next N is a kind of Draft N.It works OK if you don't expect too much. It's a little faster than wirelss G, but not 300mbps as advertised by the manufacturers. The actual max speed is 144mbps. In fact, after a short internet search, I found nobody could get 300mbps speed by any combination of a card and a router in the real world. And it doesn't seem as stable as wirelss G. Signal interruption, which is usually caused by a problem of the router or interference of other wireless devices, is not seriously frequent, but the card just stops working sometimes. Then my laptop shows a warning message like "no wifi device is detected."So it is your choice. If you want to taste a cutting edge tech in advance, try it. Or if you are not a tech enthusiast, just wait a few more months or about a year until the standardized version of wireless N comes out.

no jo :( už jsem se taky na intel stankach něco dočetl o tom že větší podporu to ma u Intel Centrio 2...
A tím je to potvrzeno, že z toho více nedostanu...

N funguje jinak, urci si optimalni propustnost vzhledem k signalu a na te jede, a jinak uz neukazuje teoretickou maximalni propustnost.
A na 300 mbit je potreba mimo, tedy na mini PCI-E kartu musi vest dva pigtaily od dvou anten.

Ehmm, co jsou to pigtaly? :)
No... jsou k ní přivedeny tři draty (modrý, šedý, černý)...

Ty "dráty" by pri blizsim zkoumani meli byt uzke koaxialni kabliky s pozlacenymi konektory nacvakle na vystupy z karty. Nebo modulu nebo jak toho prtouse nazvat.

aha, tak to jsou pigtaly :idea :)
no ale jsou 3 a ne dva.
Signal mam 100% notas mam metr od routeru.
No a existuje teda modul WiFi do notasu (mini-PCIe) u ktereho bych vytahl více jak tech 130Mbs?, nebo je to proste zatím maximum co se dá z N -kových síti dostat?

U wifi jsou realne prenosove rychlosti cca 1/2 teoretickych, takze vic jak 150 to nepojede.
3 vystupy na antenu by odpovidaly 3x mimo, to je idealni.
Vic toho nejspis nevymyslis, da se jeste pohrat s nastavenim routeru, zvolit lepsi kanaly, a dalsi, ale na strane notebooku uz neni co zlepsit.
PS: Ja mam 2 rourery proti sobe pres jednu mistnost a ma to 106 mbit.
