Re: New y510p with a wifi problem

2013-07-30, 19:52 PM

I just want to say that i also have the exact same issue with my Lenovo y510p. The Wifi drops off after a couple of minutes. It says that it is connected but it is not. I need to Forget Connection and re add the connection each time. Yes i have tried everything suggested here.

 

I have a Netgear N600 WNDR3400 and my iPad, Samsung S3, S4, iPhone 5, Macbook Pro 2011 and Sony Vaio all work with no problems.

 

It is definitely the Lenovo y510P.

 

Lenovo please look into this issue. It is evidently widespread

 

Thank you

Have you guys tried clearing your DNS cache?

 

Flush your DNS cache by copy and pasting this code to your notepad and saving it as FlushDNS.bat

@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0

 Note that this will restart your computer so make sure to save your session first.

 

Also try the latest 16.1.0.14 drivers and see if it helps. Just scroll down to where it says "Intel PROSet/Wireless WiFi Software" and the click on the floppy drive.

 

Even on Intel forum page, there are many threads dealing with Intel Centrino 2230 problems not specifically for the Y500/Y510p. I guess the only more reliable Intel ones are the Centrino Advanced-N 6205/6235 (not the old 6230/6200) and the ultimate N 6300. The newest Intel 7260 series seem to do well in the forum threads, but it's still early to say due to being only recently released.

That did not work that you suggested. The updated drivers are not for the 2230 card.

 

The only thing that worked is to switch off wifi N completely.

 

The 2230 card does not work reliably with wifi N.

 

On the Intel boards they are saying to speak to the manufacturer, here i'm being told to speak to them.

 

At the end of the day the customer gets a laptop without wifi N that is advertised.

If flushing the DNS did not work, it means your internet connection is stable and configured properly. It all goes down to the WiFi adapter. Maybe you just got a bad batch. Sadly, Lenovo still has the whitelist so you can't even replace your 2230 with the same generic 2230 you buy online. You should call Lenovo relentlessly to change your WiFi card to another Lenovo FRU 2230.

That's the truth of it, unfortunately. I have heard that some people bought a USB wifi adapter, so that they can use their machines.

I wouldn't go to the USB wifi route. You have warranty and the right to replace the card from Lenovo if it becomes defective

To be realistic here. This is what happens when we send our laptops back to Lenovo (feel free to search forums from reports of those who did)

 

1) Lenovo wipes the laptop and reinstalls the OS

2) Lenovo tests that the wifi works (which it does for a couple of minutes before dropping)
3) Lenovo sends laptop back to the customer

 

Result: Customer receives wiped laptop and issue still occurs

 

I'll only go through the above if Lenovo states they will replace my network card with a card that is not an Intel 2230.

This has been a real problem for a while but...I'm quite sure I have found the solution! In Device Manager/Network Adapters/(your wireless)/Advanced there is a setting called "Roaming Aggressiveness". What this does is try to balance performance and connectivity. On my network (and I'm sure most others) there are several wi-fi possibilities, so when performance drops on the primary network it disconnects and tries to find another network. Of course, the other networks aren't connected so the wi-fi goes belly up. I have set this option to "lowest" so the wireless client will not roam (looking for another network). I haven't lost the connection all day(!) and I haven't noticed any difference in performance. Give it a try!

For those running Windows 8, a solution with problems related to drivers which has long been observed with this OS that even goes back to its beta version is to use its own driver rather than the manufaturer's driver. That is for this case, use Windows 8 driver for the wifi card. How? Just uninstall your present driver and it must be deleted (this can be realize if you boot in safe mode). After that, reboot and just let windows discover the card and install its own driver. You don't need to do any tweakings.

Re: New y510p with a wifi problem

2013-08-12, 20:01 PM

Just Purchased a Lenovo Y510p with the Dual GPU.  My WIFI connects fine but is not very stable.  I am very close to my router and have tried on multiple routers but continue to have the same problem.  I have read the forum and have tried a few things but so far I am still getting a bad WIFI connection.  I am running a Linksys E3200 router.  I have tried to disable the N capability on the Y510p but that still did not work.  I have a windows xp toshiba that is 7 years old connected to 54g that can load websites faster than the y510p.  When I am gaming of course I can notice it the most.  Its almost like I am getting spikes every minute.  My ping will jump from 35 to 200 then back down.  I am using a Bluetooth mouse but I have tried it with a wired mouse and it seems to have the same problem.  I have updated to the latest driver and still the same problem.  I will try a few more adjustments to the adapter settings but I believe it may be a heat problem or a defective WLAN NIC.  Anyone Suggest contacting support and trying to get them to send me a new WIFI NIC ? I don't want to go through the hassle of returning the laptop just to get it back in the same condition.  Again note my wifi never disconnects but seems to have latency/ LAG problems.

 

Today I will try:

Uninstall Mcafee.

disable Roaming Aggressiveness

Remove my WPA2 security from my Router. 

 

I will post results if any of the following work.
