Hello all,

Few days ago i bought E4200 to replace my old WRT54GS,

So far i am happy wit the product.

I am running DD-WRT v24-sp2 (06/14/11) big on it.

I have a few questions about configuration.

To be honest, never before i used DD-WRT, but so far i love this firmware and i will be making donations to programmers, they are doing just a great job.


First question is about Wireless setup.

My Laptop WiFi card is Intel WiFi Link 5100 AGN.
For some reason i am unable to connect my WiFi to 5GHz at 300mbit.

I am able to do this with 2.4GHz and i am most of the time getting full speeds, even in other rooms of my apartment.

I installed latest drivers from inte, still doesn't help. I tried to switch channels around, still doesn't work. What could be the problem?

Here is from status page for 5 GHz:




What could i do to increase speed?
Should i get new USB adapter? I was thinking about Linksys AE2500, is this adapter recommended? or, is there any better in that price range, about 30-50 bucks without tax.

My second question is about USB stick\HDD plugged in to router.

I enabled:

Core USB Support
USB Printer Support
USB Storage Support
Automatic Drive Mount

Under Samba i enabled: samba, set the workgroup, gave permissions ...

When i go to My Computer under network, i don't see this share.

Thank you for reading and support.

If you can help me, or point me to right direction, please do

Best regards

Just to add, that today, even my 2 GHZ setup is jumping from 80 to 300 mbps, different channels.

Last night, when i was doing all tests, it was steady at 270-300mbps.

Thanks

5Ghz doesn't work as good as far as the 2.4Ghz radio as it's an inherent limitation of the frequency. Higher frequencies don't travel as far. You wont see the same speeds and buying another USB dongle wont help much. If you go closer do you get full 300Mbps? I have the Intel 6300 and i get 450Mbps but my place is smaller - ~800sf. It also depends on what's in your walls

Anyways, I mainly use 5Ghz not for range or speed but because it's free from interference. I have about 20-30 2.4ghz networks here so i use 5Ghz to get full speeds of my internet wirelessly.

I get great results at 5GHz (100+ mbps transfer speed, two rooms away) with the Intel WiFi Link 5100 AGN and the E4200. I did just go back to stock firmware due to the 2.4 GHz wireless signal degradation problem on later DD-WRT builds which even improved my speeds on 5Ghz by 10-20 mbps.

Do get the latest driver from Intel which is version 14.2.0.10. I have the best results with driver configuration settings:

802.11n Channel Width for band 2.4=Auto
802.11n Channel Width for band 5.2=Auto
802.11n Mode=Enabled
Ad Hoc QoS Mode=WMM Enabled
Fat Channel Intolerant=Disabled
Mixed Mode Protection=CTS-to-Self Enabled
Preferred Band=Prefer 5.2GHz)
Roaming Aggresiveness=Medium
Throughput Enhancement=Disabled
Transmit Power=(Choose option #3 or 4)
Wireless Mode=(Choose option #5 or 6)

Thanks all for info.

I just bought Linksys AE2500 and i am getting full 300mbps all the time, it never dropped. ( I am going to return this back to store after i do tests )

Linksys in Properties has tons of options, and i have no idea what to enable\disable there, etc. but maybe i shouldn't touch anything, if its 300mbps and not dropping?



I am going to try this USB on my laptop as well to see whats going on, currently testing on my desktop.

Just did speed test with this new Linksys USB:



vjbalex, for some reason i am only getting 54mbit with those options :\

What do you guys think?

Thanks!

I got all kinds of hints from the Wiki and ended up with the following. I use different SSIDs for the 2.4/5GHz bands. Below are settings for 5GHz that I used when on DD-WRT. Adjust Sensitivity to 2 times farthest distance from router for any connecting device. Use TX Power 28-40. Connection speed does not really matter as long as it is decent. Play with those settings until you have the best throughput.

Thanks a lot !

Will test it later today after the work.

Will let you how it goes

I just tried your settings, as soon as i leave my room i am starting to loose signal like crazy.

Intel card settings are as you advised.
Driver version: 14.2.0.10

Here are my router settings for 5Ghz:





All those stats are when laptop is in the room where router is.


Please advise

[vjbalex]

Connection speed usually drops when moving away. The idea is to to adjust settings to get the best throughput possible (like when downloading or transferring a file from another device on your LAN)

I can think of only three more things to try:

Your setting on the 2.4 GHz band is Mixed for a-b-g-n clients. Try NG-Mixed or N-only/G-only depending your devices. Make it as limited as possible according to your client needs.

It's usually recommended to make SSID all one word with no spaces e.g. DiS_5G

Set WD1 (5GHz) Advanced > Preamble to Auto.

The 2.4GHz N performance dropping over time was experienced by me and others in this forum with the newer DD-WRT versions which is why I went back to the recently released Ver.1.0.03 (Build 14) stock firmware for now. 2.4/G-only and 5GHz/N-only were ok.

I have found NO third party firmware that beats the stock performance in speed/throughput. That might be your next course of action.

[s-f-r-j]

Thanks for all info.

I am still getting poor results.

I might try stock firmware as you recommend.

Now i even think that i should went with different router? I am still able to return this router to the store and get something else, but not sure what.

Regards
