Bad wifi connection on Samsung NP900X1B

Hello,

I just bought a Samsung NP900X1B and it is a beast.

BUT, the wifi is crap!!
My room is far from the router, but my last Lenovo X220 was connecting to internet without problem. With the Samsung, it connect poorly..sometime disconnect.. it's a shame!

So, I bought a new Intel advanced-N 6250 wifi card and installed it in my Samsung. Not even better..

What can I do now? If the Lenovo can do it, the Samsung should too..

Thanks!

 

After playing with my MSFT Samsung NP900X1B for about 2 weeks, I have came to the same conclusion. Wifi download speed is horrible. FYI i am using the latest 15.0.7.5 drivers. Distance from router (downstairs) to my room (upstairs) is ~ 40 feet

Series 9:
Ping: 35 ms
DL: 3.21 Mpbs
UL: 3.96 "

Ping: 25 ms
DL: 3.02 Mbps
UL: 4.07 "

Compared to Envy 14 Radiance
Ping: 35 ms
DL: 8.25 Mpbs
UL: 4.13 "

Ping: 25 ms
DL: 7.01 Mbps
UL: 4.16 "

Anybody else having the same problem? Any suggestions on how to improve this? Thanks

I love everything about the Series 9 except for Wifi speed. If this isnt fixed I am afraid I have to return it.

 

Does setting wifi to max performance (when on battery) in power management help at all?

 

Yes, I did.. and it doen't help much. It sould be the antennas that sucks..I don't know.

 

Although I have the NP900X4C, I too am having a major issue with degrading network speeds with the Intel Centrino Advanced-N 6235 network/Bluetooth card. I am running a clean installation (having upgraded the dismal 128Gb with a Crucial M4 256Gb) using only the drivers provided by Samsung and all other system aspects of the laptop are working to specification. My issue is that on a sustained download (either being pulled down from the local network or the internet), over the period of 20-40 seconds, the download speed, after commencing at 1000-1400kb/s drops to the point of a mere trickle at 40-80kb/s. I have duplicated this degradation on 3 separate networks/Access Points, all with very similar results. If I disconnect and reconnect to the access point, download speeds again start at 1000-1400kb/s, only to degrade shortly there after.

Note I have no issue connecting to an access point, that part is, thankfully, "as per the book".

I have tried uninstalling the Samsung provided 6235 drivers and installing the latest drivers V15.2.0.19 (as well as the Bluetooth driver V2.2.16.30255) from Intel and tried adjusting the power management settings, but no change. I have even ordered a replacement Centrino Advanced-N 6235 (should arrive after 13-Aug), as I'm having difficultly in understanding how this can be a software only issue.

At this point, any thoughts and/or suggestions would be most welcome & appreciated.

Thanks

I saw similar issues when first testing my X4C and it couldn't keep up with the home internet speed so I just plugged in the network cable. I've not noticed any problems while away from home but I'm not connecting to fast networks.

(i) Have you tried disabling Bluetooth in Easy Settings? Then (ii) try fiddling with the settings in the WiFi adapter properties.

• Regarding the three different networks, were those networks at different locations like work, home, the coffee shop, etc.?
• In all of your testing, were you using the same download?
• What are you trying to download? A big .ISO image, video, or other?
• What site is the download source? Are you confident the source download server is sending the data properly?
• If it isn't too confidential, can you supply a download link for our testing?

 

Yeah, yeah, necroposting I get it. Better to get the information out there to everyone who has this problem.

Just got an NP900X1N, overall impressions: Eh, it's decent. Thickness, battery, screen, heat, all leave areas for improvement (they're alright, 7-8/10). Speakers are surprisingly loud & nice, as is the SSD. Keyboard, ports, build quality are all adequate. Must use two hands to open the lid. I can see how it would be impressive when it came out (I couldn't afford it at the time), currently it's a decent portable machine & I'm happy with it.


The wifi was downright embarrassing however. Initially the laptop was seeing ~0.67-1.0Mbps download and ~0.50Mbps upload (speedtest).


My solution (NP900X1B-A01US) [requires a basic familiarity with computers]:

0) Create a restore point.

1) Use Aida (google Aida hardware) to find out what model wireless network adapter your model has. Aida // Devices / PCI devices (e.g. Broadcom BCM43225)

2) If you have a Broadcom BCM43225 I will share my path to adequacy/satisfactory performance:
-First tried updating drivers through windows, no change.
-Second tried changing settings (power modes, wifi settings, bluetooth settings, etc.), no change.
-Third looked for driver updates online. Broadcom seems to focus on selling their hardware to companies like Samsung and letting others worry about driver updates/product support. I didn't find any recent drivers through either company, but I did find:

Lenovo link to vers. 5.60.18.41 which took speeds from 0.67-1.0Mbps to ~3.3Mbps download

Adequate for basic browsing, but still not satisfied. So I found Third party link to vers. 5.100.249.2 which brought speeds up to levels comparable to the other devices on the network ~5.1Mbps. I don't have access to faster networks at the moment unfortunately, but that's enough to stream HD without problem.


If you are experiencing wifi problems but have a different wireless network adapter or different model Series 9 just plug the wireless network adapter model number into google along with "driver" or "driver updates". I came across my solution after a few evenings of trolling for "BCM43XX driver windows 7" and similar. I was preparing to buy a new Intel wifi adapter but reviewers of that solution are mixed at best and this is $30-$100 less.


If you appreciated my help I like hamburgers.
