D-Link DIR-655/825/855 and Intel 4965AGN Wifi connection limit on HP 8510p

Hello all,

I have a HP 8510p laptop with Intel 4965AGN and a Linkys WRT54GL v1.1 "G"" router and I plan to buy a D-Link DIR-655/825/855 "N" Router. After searching on a net i have found that the 4965AGN max speed is around 130Mbps with D-Link DIR-655 WPA2/AES settings although the router can handle 300 Mbps as well.

Can somebody give me information about the following:
1) Does still the 4965AGN "suffers" from that connection limitation?
2) If I buy the advanced version (D-Link DIR-825/855) can I connect with 300 Mbps?
3) If answer is no for 1 ans 2, what is a good "N" Router for me that works with my 4965AGN on 300 Mbps?

Thank you for your reply in advance.

Bests,

I have a HDX Dragon with the 4965 and the DIR-855 and the Linksys WRT610n.

DIR-855- 270 Mbps, slightly greater range...hiccups occasionally. May be due to european version and firmware.

WRT-610n- 300Mbps, smoother operation. I know others say it drops signal, but with latest firmware it is rock solid.

You have to use AES encryption, wide-channel and you're in there.

Both of these routers are simultaneous dual band. I recommend them if you have G devices on your network as well. Otherwise a non-dual band router will always default to G (or other than N). If your lappy is only one on network, any of the routers you mentioned should work fine.

 

To get above 130-150Mbps you need to enable wide 40MHz channel in both wireless router/access point and wireless card (in your case 4965AGN).

If you buy DIR-655 then yes, your 4965AGN will still 'suffer' from that sort of connection limitation.

The problem is DIR-655 is a 2.4GHz band only wireless router. Even if you enable its 40MHz channel, 4965AGN could not use it because 4965AGN could only operate 40MHz channel in 5GHz band. So, in order to get above 130-150Mbps you'll need wireless N router which could operate in 5GHz band.

4965AGN should be able to connect up to 270-300Mbps with dual band wireless N router such as DIR-825/855, as long as the 5GHz wide 40MHz channel is enabled in both 4965AGN and DIR-825/855.

hovercraftdriver has mentioned some. And you could always look at SmallNetBuilder Wireless Charts for reference. Be sure to narrow the charts by checking the N standard and Dualband filters.

 

Thanks very much!

 

aidil, hovercraftdriver,

Now after hours of googeling and revirews reading i am completely lost.

Si if i am right: if i want to get 300Mbps with my 4965AGN on my laptop the best would be either LINKSYS WRT610N or D-link 825/855.

I have read completely opposite reviews about them. I like the 825 bit it has only 2 antenna, 855 has 3 antenna but expensive.

So if I want to get a router that I want to use only for N and get the 4965AGN on 300Mbps fly what do you suggest to buy? I am ready to take one of that.

Thanks in advance.

 

All 3 can get 300Mbps. DIR-825 has shorter range due the lower # of antennas (among other factors). If you need it to cover a large area it is not for you. The DIR-855 is way too expensive. The Linksys is pretty good if you just want range. However for pure speed the DLink routers are the best you can get. I have the DIR-825 because range is not too important for me. Torrenting performance is.

 

By using 2 Antennas, a wireless router can transmit and/or receive up to 2 spatial streams. So, 2 antennas is sufficient for up to 300Mbps connections as each spatial stream could carry data up to 150Mbps.

3 antennas in Intel WiFi Link 4965AGN and current wireless N routers/access points are used for better data reception and transmission.

In case of Intel WiFi Link 5300, the usage of 3 antennas is different. This latest Intel wireless card can use its 3 antennas to transmit and receive up to 3 spatial streams, which means up to 450Mbps connections. But to have this kind of connections, it has to be connected to wireless N router/access point which is also capable to transmit and receive 3 spatial streams. I don't know whether this kind of wireless router/access point has already existed.

 

If you dont need a simultaneous 2 radio router, go with the Dlink DGL-4500, dont worry about the fact that dlink calls it a gaming router and its cheaper then the 855, the 4500 is a supurb router and has range.

 

Thanks the replies again!

Finally, i ended up with a DIR-855. I could buy one for appxly. $140.

1 )So is there anything else that i have to be aware of when i will be setting it up next week?

2) I have a Linkys WRT54GL v1.1 "G"" router as well. What do you suggest to use as a primary router, WRT54GL or DIR-855?

thanks again

 

DIR-855 is a simultaneous dual band wireless router, then you could set the 5 GHz band for N only with 40MHz channel enabled and the 2.4 GHz for B/G. You don't have to use WRT54GL anymore, unless you have a big area to cover, such as multiple floors, then WRT54GL could come in handy.

 

Will be any speed impact on the DIR-855 N 5GHz if i use 2.4 GHz for B/G as well or they work independetly to each other?

 

You can expect the N network to have pure performance when it is separated from B/G network.

 

What do you mean by "separated"?
To keep WRT54GL for G and use DIR-855 for N only?

 

Routers typcially gets lower performance in mixed mode. However since the 825/855 is mixed mode you should be able to run 2.4Ghz with 5.8Ghz with no drop in performance. You will get performance drop if you mix B/G/N on 2.4Ghz or A/N on 5.8Ghz.

 

No, not using WRT54GL if it's not necessary as I've mentioned before.

Your DIR-855 is capable of simultaneously operating in 2 "separated" bands: 2.4 GHz band and 5 GHz band. So, just use its 2.4 GHz band for B/G network, and its 5 Ghz can be use solely for N network.

As others have mentioned, you'll get better performance with your N network if it's not being mixed with other standars.

 

OK. Thanks!

 

OK. I have the DIR-855 up and running. I connect to Wifi N at 300 Mbps.

I am satisfield with the speed:
CIFS: 8MB/s
FTP: 11 MB/s

3 things:
1) Is my speed OK, what are your scores with that router)?
2) If I set wifi N (or G) to WPA2 only + AES, I can not connect. If WPA and WPA2 is set with AEs, it works. Is that normal?
3) Shall I update firmware? I am not sure if it is worth to do it (bugs, future problems)?

Thanks a lot!
