help with TL-WDN4800 very very slow connection

[kicsrules]

I recently got a TP LINK TL-WDN4800 pcie adapter, the card xfers at most 512Kbps while in a tablet/phone same connection gives me at least what the bandwidth is 20Mbps.

i already tried latest drivers from here http://www.station-drivers.com/index.php/downloads/Drivers/Qualcomm-Atheros/WLan/AR5xxx-9xxxx-Serie/

since tp link drivers are very out of date (already tried them too)

i tested the card with a live version of linux mint and it goes up to 11Mbps at least.. that make me think that the drivers are the issue... but i already tried every driver available for this card :/

my setup is as follows

router FO alcatel lucent i-240w-a current bandwidth 20Mbps - ethernet 1Gbps (which there is a NAS connected)
the wireless setup is automatic (b/g/n) currently the speed that shows connected at is 144Mbps. (if i change the speed just to "n" it goes slower - the other devices are not affected)

windows 7 64bit ultimate SP1

any thoughts ?

you have the version v1 of it then there is driver from june 2014 http://www.tp-link.us/support/download/?model=TL-WDN4800&version=V1#tbl_a

 

[kicsrules]

i already tried that one, its older than the ones in the other page....

 

[scout_03]

your link lead me to atheros driver and i did a search on it for the tp-link and they dont have any for this card .

 

[kicsrules]

the chipset is atheros ar938x

edit:

current transfer speed

current driver

current signal strength

i been looking at my wireless connection with inssider and have 9+5 on channel with link score of 34 also no co channel network is 0 you have 2 the overlaping is 4 you have 12 the max rate 270 you have 144 and the signal -45 dbm you have -60dbm so you have some network around you that overlap your signal i was having the same issue before loosing internet a neibhourg was ovelaping mine that why i switch to channel 9 and my wireless device is a n-10 asus usb one .

 

[kicsrules]

the current channel is the least interfered, at the same distance (with a laptop) i get 20Mbps in speedtest and in LAN transfer around 5-6 MBps ..... tablet/phone is the same it does high speed transfer so i already discarded the config in the router :/

 

[scout_03]

could you raise the router on a shelf and see if you put the computer on the desk that the signal is getting stronger the other option is to get a power line wireless extender set from the router to the desktop .

 

[kicsrules]

yeah, the powerline is not going to happen, i want it to be all wireless... the pc is connected through a UPS and there is no other socket in the wall for the powerline extender, the current link score that i have right now is around 80 (when i get home i´ll post it.. i tested it again with linux mint live cd and it did perform well... don't know if its the drivers or windows ultimate edition or what... i've read that the problem is with windows 7 ultimate edition 64 bit ... (only read about 3 other similar problems) and that is, another person figured out that since its 5ghz compatible is always scanning for that 5ghz band and thats the main reason it drops connection...

 

[scout_03]

i did some search and the 2,4 signal is stonger then the 5 one but less faster so for a strong one use 2.4 mhz .

 

[kicsrules]

i think i've identified the problem here, the only ppl that have the same issue is because they have windows 7 64 bit ultimate... i'm going to try with win 7 64 pro to see if that is the case ....

 

[scout_03]

alll the win 7 x 64 use the same driver .

 

[kicsrules]

but the way it handles that driver, is it different ??? (pro and ultimate version)

 

[scout_03]

you could link me where you find those details about the driver acting in a way in the ultimate to another from the premiun also i read back post and you have 12 overlaping network around your place so it would be a good thing to try to boost your wireless signal .

i couldnt find the other ones (dont have much time) but theres a coincidence with win 7 ultimate

 

[scout_03]

that is strange they sell stuff and not even able to give driver up to date sothe best thing would be to suggest to the one who use this to install the atheros driver thanks to put that on this will serve other with the same issue ,i would like to see if a official representative from tp-link could answer us on this .

 

[kicsrules]

even in their forums, they dont offer support..... anyways, i bought an asus router (dual band) and i just connect to the 5 GHz band (with another name than the 2.4 ghz) and its cool, not as fast as they claim, but enough.... (at most 12MBps/around 100Mbps)

 

[scout_03]

great that you could use the 5 ghz band i use a old linksys wrt 160 n and have a 30 mb on down and 10 up from my provider and it is the same on wireless .

 

[kicsrules]

yeah but, even though it says its connected @ 450 Mbps it only transfers at most 100 Mbps... :/

 

[scout_03]

if you go directly on the modem with the computer you should have full speeed if the nic card could handle it .

 

[kicsrules]

yeah, i know that but the thing is that from a 450 mbps connection, at least a 200 mbps connection would be fine, the modem is around 20 ft from the pc, 5ghz is in the 40 mhz bandwidth no overlapping signals (no other 5 ghz signals in the building) .... is there an option to connect simultaneously to both 2.4 ghz and 5 ghz (different ssid ) ????

wired is not an option :/

before this it was wired (1000bmps ) but the new modem installation moved the modem far away so right i went wireless..

 

[scout_03]

you could use both and set the modem to transmit in wide range with on ssid .

 

[kicsrules]

can you elaborate ? i put the same ssid on for bot 2.4 ghz and 5 ghz ?? set it on 40 Mhz bandwidth ???

 

[scout_03]

the have to be on the same router for the 2.4 ghz and the 5 ghz and yes use the wide channel 40 mhz if you do not use the same router they could conflict .

 

[kicsrules]

made it like that and got worse, two different ssids and transfer tops 11 Mbps, i think i'll leave it like that thnx anyway
