I don't think there is a "best" router that matches that adapter. I have just started using the 5300 AGN as the standard wireless test adapter and results look good with both Atheros and Broadcom-based routers.
Hi, I am new to these forums. I recently got the itch to revamp my home wireless network system and upgrade it to latest Draft N 2.0 stuff. Been buying and trying various routers and adapters thus far. As I recently learned about the new Intel Pro Wireless Link 5300AGN mini PCIe adapter as the up and coming card to use for future multi-streams 450Mbps capability, I bought a few of them to replace all my old laptop internal adapters.
Now, the main reason I wanted to post here is because I just noticed a quirk with these Intel 5300agn adapters on the 2.4Ghz band when connected to my Linksys WRT610N or my WRT320N routers. As noted elsewhere in your SmallNetBuilder columns (or forums) this 5300agn adapter unlike the older Intel 4965agn adapter allows you to connect at 40Mhz bandwidth as well as 20Mhz bandwidth thus allowing your 2.4Ghz speed readings to go above the 144Mbs limit. It can now go up to the 300Mbps with my wireless-N routers.
You can turn this wide band 20/40Mhz mode on in the device driver settings in Windows control panel. (you cannot do this for the older 4965agn card).
But lo and behold, I ran into a problem with this 2.4Ghz wide-band capability running the 5300agn card. All runs real well when there are no 802.11B clients connected to the network. As soon as I connect my Sirius SL100 radio to the 2.4Ghz network for internet music, this Intel 5300agn connection (in Wide-Band mode) totally crashes. It starts dropping packets and ultimately fails and disconnects. I view this as a bug! It should not drop connection but rather should re-negotiate and adjust itself to keep on going.
All my other wi-fi adapters are unaffected by the mixed mode when my 802.11B client joins the network. The 5300agn drops out completely and fails when it is set to 40Mhz wide band mode. I got worried that my Linksys routers were buggy and dropping connections all the time... untill I figured out that it was this 5300agn card not compatible with mixed mode networking.!!!
To fix this quirk, I put the 5300agn adapter back to only 20Mhz bandwidth on 2.4Ghz band. This way it has a top speed limited to 144Mbs but it will then work fine when an 802.11B device joins the network.
Was this clear? Just FYI in case you have not noticed this quirk about the Intel 5300agn card.
