Intel 5100 and Linksys WRT300N

I have searched around and found similar problems but not this specific one.

I just purchased a new HP HDX16t which comes with the Intel WiFi Link 5100 mini-card AGN installed. I have had a Lnksys WRT300N router for a few years now. I typically received about 270 Mbps speeds using a Linksys wireless N USB card on my old desktop. Now with the new laptop I can only get 54 Mbps!!! I have tried a lot of the suggestions I have seen (upgraded to the latest firmware on router, no security, N-Only mode, etc.) but no luck!!

Has any one out there managed to solve this problem? Should I approach Linksys on this? From what I can figure out, it seems to be a problem with the adapter card, not the router. Andy Help would be appreciated.

Have you tried switching to 5ghz wide band? 11n prefers WPA2 security

There has been a lot of request for help with connection problems with the 5100, the 5300 seams not to have these problems. If I recall the problem was corrected by switching wireless managers. Do not recall if it was MS or Intel's, but in any case you do not want both loaded at the same time.

Have you searched the forum for the 5100?

 

I have searched everywhere and read quite a few posts here. I haven't yet come across anything about the "wireless managers". I'll keep looking.

Thanks for your response!

 

I found this on the Intel website:

Symptom(s):
Client device's WiFi data rate will not exceed 54 Mbps when Wired Equivalent Privacy (WEP) or Temporal Key Integrity Protocol (TKIP) encryption is configured.

Cause:


The IEEE* 802.11n Draft prohibits using High Throughput with WEP or TKIP as the unicast cipher. If you use these encryption methods (e.g. WEP, WPA-TKIP), your data rate will drop to 54 Mbps. The Intel® WiMAX/WiFi Link 5350, Intel® WiFi Link 5300, Intel® WiFi Link 5100 and Intel® Wireless WiFi Link 4965AGN client drivers connect using a legacy IEEE 802.11g connection rather than failing to connect altogether, which complies with the IEEE 802.11n draft.


Solution:


Contact your WiFi access point (AP) or router manufacturer to download the latest firmware version, or to obtain information on particular models supporting High Throughput.
Disable 'packet bursting' or similar feature that may be enabled on the AP or router.
Configure the WiFi client device's profile to use Wi-Fi Protected Access* (WPA2-AES or WPA2-TKIP). You may also choose to configure an unsecured profile, but this option is NOT recommended.
Configure the AP or router to match the client profile.

Note: Some AP or router manufacturers may not have updated firmware solutions for devices sold outside of the United States.


This applies to: Intel® WiFi Link 5100
Intel® WiFi Link 5300
Intel® WiMAX/WiFi Link 5350
Intel® Wireless WiFi Link 4965AGN

Sounds like I am out of luck if I don't switch to WPA2, but I have G devices on my network and I don't think they support WPA2.

 

Btw, my Linksys wireless N adapter did 270Mbps over WEP, no problem.

 

For the most part Wireless Adapters w/ 802.11g does support WPA2 security. I'll say 99% of them.

 

I have a Sony Z-series with the 5100 series, but everytime I upgrade my Linksys WRT300N to Wideband N-wireless (with WPA) it can't connect. Any suggestions/thoughts? I'm running Vista (not that it matters) and it's working like a charm on G, but no dice on N.

 

I too have problems. I have just bought a new Intel® WiMAX/WiFi Link 5350, because i had expected to achieve highspeed-connection.
My laptop is a 7730G.
I am connecting to a WAG300N-router, so the hardware for more than 54Mbps should be in order. The security is set to WPA2 security.
Could it be that the two different brands "dont like" eachother ?

Thankyou for your effort.
Now I have reinstalled newest firmware, and having resetting it.
My settings for wireless is : ADSL2+___DDNS disabled___NAT enabled___RIP disabled___Wireless network mode mixed___Wide 40MHz___Wide channel 9___Standard channel 11___Security WPA2-personal / AES
But still only 54Mbps, and I have no clue for what to do ??

Have you found a fix? Does router have only 54Mbps speeds with other computers? Do you have any means to another Draft-N router? Do you have any other comps connected and are they at wireless G?

Just some info:

mixed mode??...you have it on N only correct?...if not it downgrades to the speed of b or g if it's set for all 3

 

#sparkyman2000
Yes, I also have 54Mbps with my other laptop (I am not using them at the same time). I currently don't have the opportunity to try another Draft-N router, but I will try to ask around to borrow one.

In the "Basic Wireless Settings" tab, "Network mode" there is not an option to choose only N.
I can choose between "mixed" and "disabled".

You got me thinking. I know that you would have to have a dual band to run both N and G at the same time but switching one computer with G and than right away switching to the computer with N I dont know if it would lock it into G mode. I only have a dual band router now. So if someone else could try that would get your answer.

 

#sparkyman2000
No, what I mean is, that the previous laptop i had was connecting at 54Mbps, therefore (among other things) I bought a new laptop, and swapped the wifi-card in this, to a Intel 5350.
I have not used them simultaneously on the wireless.

Added after searching: I think it's maybe the reason:
According to this, my WAG300N is not approved ?.
