Lenovo U510 wifi issues

Hi, my problem is that wifi latency is "jumping". I have like 5 mins 5 ping and then until i turn on and off wifi it goes on 600 ping. I tried it on my other laptop and there is no problem with ping on same wifi. I saw same topics that people have problems with this type of laptop too. I wanna know if there is any wifi driver or something to fix this issue. I own Broadcom 802.11n Network Adapter.
(Sorry for my english)
Looking forward to hearing from you,
Jaroslav Miko

really nobody?

Lenovo S860 wifi issue

Hi,
I just bought lenovo a860 2 days back....and found updates system with kit kat 4.2.2 version which I instantly upgrade without checking phone performance before update.
I just realize now that i hv an issue for connection with wifi.....it can connect with any wifi network (i tried 3 different wifi source), it was connected.....and i try speedtest with speedtest.net....it also working well....it show download speed n upload speed.
But all those 3 connected wifi didn't deliver connection....i can't browse anything, simply said the internet connection is not working while it connected on wifi network.
Is there someone hv same issue with me? And for Lenovo's admin any suggestion to resolve this issue?
Many thanks,

Hi bhaveshvac,
Glad that you are not facing any problem with Touchpad and Wifi like the one discussed below. Couldn't believe that there is no problem with laptop. Are you still facing any problem?

Lenovo U510 Broadcom Wi-Fi adapter low speed!

Hello,
I have recently purchased a Lenovo u510 with i3 processor and hd4000 video card. I have installed windows 7 on it and I have issues with the wi-fi card. I have used the drivers from the Lenovo support website, and the speed barelly exceeds 3mb/s. Usually is 2,5 and much lower lower. I have a HP probook put in the same place and it has a speed 4 times bigger.
I have tried also windows 8 and it has the same problems.
I am very sattisfied with this laptop, but this wifi issue drives me crazy.
I really need help, seems like the problem is with the wifi adapter, Broadcom. An Intel centrino one it would be better.

Hello,
Should I consider that this is the max speed of this laptop? I have put the U510 and HP probook from work near the wireless router.
The the maxspeed for lenovo was 4,5 mbps and the max speed for HP was 10 mbps(because thats the max from my provider).
Why that big differece between a Broadcomm wifi adapter and a intel centrino one?
Does the aluminium case have problems?

I keep running into wifi issues with this laptop, I've troubleshooted some but still I'm having issues with (limited connectivity) AND it would connect but webpages would not load.
for the first problem it was the power profile which i changed, I've updated the drivers on the laptop, and updated firmware on my router(which wont matter if i take my laptop to starbucks.. its not like i can update their firmware everywhere i go..). It is still giving me limited connectivity(even when other laptop/ipod are able to use my wifi fine)
I recently bought this (owned for 2 weeks) and i'm so fustrated, i cant even work on things without the internet. any help would be much appreciated.

Hi all,
thanks for posting your concerns. I understand your frustrations towards this issue and would like to see if i can assist in anyway. As you may already know there are a number of things to consider when it comes to the wireless and I'd like to narrow down the issue, if you'd be wiiling to work with me for a bit. Based from what's posted here, I'd like to suggest the links below to start with. From there we'll try to narrow further the issue. Though I can't say for certain at this point what I'd suggest at the moment if you haven't updated your wireless drivers, I'd suggest to uninstall the current drivers you have reinstall the drivers from the link below. If the driver versions are the same please skip the update of drivers and follow on the with the other 2 sgeestions from the links below.

Lenovo G505 Wifi Problems - Limited Connection, No Connection, and Dropped Connections

Some forum members have reported a variety of Wifi issues with their G505 laptops. Their reports range from showing "Connection is limited", to Wifi connections dropping repeatedly, to being unable to make a Wifi connection at all. I combined multiple threads in order to assist forum members with troubleshooting solutions.
If your G505 was upgraded to Windows 8.0 or 8.1 and then lost connectivity, or you recently purchased a G505 running Windows 8.0 or 8.1 and are unable to connect, try following the instructions posted by Vikramsbox to restore the connection through the Lenovo Communications Utility.
For non-Windows 8.0 or 8.1 users, start troubleshooting with the basics:
The most recent WLAN, BIOS, and Power Management drivers from Lenovo can be downloaded here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-g-series-laptops/lenovo-g505-no...
It is also good practice to verify your Wifi is activated by following the instructions from Neokenchi.
Check Power Management settings to ensure your laptop isn't turning off the Wifi as noted by Dannyk1.
Check to see that Airplane Mode is set to OFF by following the instructions provided by Shiv_K.
After trying those steps, if you still experience a Wifi issue with your G505, other troubleshooting steps have been noted in this thread. This includes a whitelist of accepted replacement WLAN cards posted by Topmahof and a 3rd party driver which resolved wifi issues for Miila and Jessemck125. Please note that while Lenovo does not support 3rd part drivers, it may be an option to consider if your laptop is out of warranty and none of the suggestions in the thread resolve the issue.

First computer was a 1980 Commodore 64 from Radio Shack/ GEnie SFRT member from 1993-1996

First is to update your Atheros/Broadcom driver for your G505 here:http://download.lenovo.com/consumer/mobiles/wlan117w8.exe
From what I understand, the situation is that you get limited connectivity while your other devices that are connected to the router gets uninterrupted internet access.
After updating your drivers, you can try to 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.
Here's the link that explains the benefit of flushing DNS: http://www.sevenforums.com/network-sharing/144365-network-posting-tips.html

I also have other issues with the dolby system (I see others have the same problem )and my touch screen is not working.

Hi-
I am also running into the same issue with my Lenovo U410 and it is really frustrating. I also have Centrino Wireless chip with driver version 15.10.3.2 and I have windows 8.1
I bought the laptop from Costco and was having similar issues. I sent it back to Costco Concierge who apparently replaced the wireless chipset on this laptop but now I am getting this issue.
Any help will be greatly appreciated.

Lenovo U510 screen problem

I bought a lenovo U510 ideapad 4 months ago at BestBuy in Canada. It recently started to showing a screen split into 4 sections everytime after installing windows updates. The only way I'm able to get rid of the 4 sections is by refreshing the laptop and taking a risk of loosing all my files. Also when projected to a larger screen, it doesn't show the 4 sections. I'm confused about whether the problem is with the hardware or with the software!
Please help me, what could be the problem????
#worried!

Hi Tsefuthi,
Welcome to Lenovo Community Forums!
I’m sorry to hear that there is display related issue in your U510 Laptop, as this issue occurred after installing “Windows Update” in the computer. I suggest you to perform System restore in the computer and check if the issue persists. Below are the links to perform System Restore in Windows 7 & Windows 8.
System Restore for Windows 7
System Restore for Windows 8 & 8.1
Hope this helps!!!
Do post us back if the issue still persists.

T440P: WiFi issue

Hi everyone. I am new in the community so thanks to support this big community.
I am working for an It company where everybody use Lenovo Thinkpad, series T.
I am facing some problems with the ThinkPad T440P, it loses from time to time the Wifi adaptor, after restart and restart, It finds again the interface and it works fine.
I have found some discussion about this issue here, but nobody suggest a properly solution about it. Is there someone know manage a solution?
In my opinion, almost every lenovo has several issues about the drivers interfaces and hibernations.
In addition, may be, this place is not the properly place to ask this question, but, I was trying to create a ticket in lenovo for warranty laptop, lenovo sends me to IBM, where I have to purchase a kind of services in order to have some support.
Thanks
kind regards.
Solved!
Go to Solution.

Try this driver.
Go to Control Panel and uninstall Intel ProSet. Restart. Install the driver. After the driver is installed, open the properties of the wireless adapter.
Set channel width to Auto on both 2 and 5 bands
Ad hoc QoS mode, WMM enabled. If your router has this setting, enable it.
HT Mode: VHT
Roaming aggressiveness Medium
Transmit power Highest
Wireless mode a/b/g
In Power Mgt, set "allow computer to turn off this device" to enabled.
In the router, set encryption to WPA2 PSK Personal. Don't use TKIP, it maxes out at 54 Mbps.
These are my settings and my T440p with that adapter works fine. I've tried all of the subsequent drivers and they've all had problems with waking after sleep. If you get your system stable and working to specificiation, leave it alone. A newer driver won't make it any better.
Note: I'm also connecting to a newer AC router. I suspect that not all routers perform equally well with this part.

I reinstall the Yosemite due to the wifi issue, when finished, the iMovie was not installed, I try to download it from app store, but it's not free. How can I get iMovie back?

I'm using a mid 2014 13" rmbp. I reinstall the Yosemite due to the wifi issue, when finished, the iMovie was not installed, I try to download it from app store, but it's not free. How can I get iMovie back?

It's something to do with the main user account (not iTunes account) on my Mac because I logged in with another account and it downloaded fine, I installed it on the HDD and even though the date in App Store was 16th October 2014, it is the full installer of 10.10.2.
To try to resolve this problem, I have copied the installer app elsewhere and deleted it but App Store still will not allow me to download it with my main user account yet just allowed me to update iTunes.
I had a brainwave last night that it might have been related to me changing the default downloads folder to one not on my boot drive (to save disk space on my main boot drive) but having changed it back, tried again, rebooted and tried yet again, deleted my App Store preferences. nothing has worked.

WiFi issues with iPhone 4S & ios 6 update

Okay here is my issue...
I've been reading alot of issues that people have with connecting to WiFi with their new iPhone 5, iPhone 4S or other devices but I have no trouble connecting to WiFi at all. My problem is that WiFi wont 'work'. The WiFi I'm hooked up to at home doesn't let me do basically anything that requires internet.
I can get on the Facebook app fine and my newsfeed loads but I can't see Facebook notifications, upload photos or videos, read inboxes, look at photos, its very slow etc.
I can't get into the App Store or iTunes at all. It says it 'Cannot Connect to iTunes Store' when I try.
I can't upload photos onto Instagram
Currently I'm into the Simpsons Tapped Out game and I can't go onto it at all.
And there are a few other minor issues I am having.
All these things I can do with my Telstra 3G network however and it ***** because I want to use and do all these things but I have to use my 3G and I've just recently gone over my data monthly usage and been charged extra which I'm not happy about.
So is anyone else having these issues or is it just me and I'm stuffed? I'd REALLY love some help.
I've been lost with what to do because as some are having WiFi issues as well, mine isnt the same and it's hard to find answers or just other discussions.
Please Help!
Thankyou.

I am having the same issue since updating to iOS 6. It has been noticeable on my iPhone 4S and a little less noticeable on my iPad 3 but I think it is happening on the iPad too. Very annoying problem. One way to get it to work better is to re-boot your phone. It will work for awhile then and then eventually not be working anymore and you will need to re-boot again.
Just to be clear with everyone - the iPhone looks like it is connected to the wireless, it gets an IP address but can't transmit any data. Device: iPhone 4S, OS: iOS6

Wifi issues with iphone not responding

Phone: iPhone 4s.
This issue started approximately two weeks ago. My phone initially started with the Wifi connection greyed out, I followed the appropriate steps to resolve this issue, and was successful. Now I can turn the wifi connection on without problems, but my iPhone will freeze (delay), then return me to my homescreen. Occasionally I do automatically connect to my known wifi, but then will disconnect and return to 3G. If I make an attempt to go to settings to manually reconnect, the phone again freezes. The phone seems to freeze after I click settings, then when pressing Wi-Fi, the bar turns dark bold, but freezes and doesn't open. I then have to click my home button, return to the main menu. Also if I open an app during the seldom opportunity my phone is connected to wifi, the phone will disconnect, return to 3G and freeze. I have rebooted my routers, forgot networks, reset network settings. I have thought about resetting the entire phone, but my phone will not stay connected to wifi long enough for me to back up my data to iCloud. I am thinking of stopping into my local verizon store, but I think they will redirect me to an apple store; which is 35 miles away. Of course the problem with me not connecting to Wi-Fi is my increased use of data. Now I am over 75% for my monthly usage with 2 weeks remaining, and do not see justification in possibly having to pay the overage fee. Many times when my phone freezes due to these wifi issues, or will not respond, I have to do the manual power/home reset. In conclusion, I need to figure out how to maintain my connection to Wi-fi, and stop my phone from not responding when I open my wifi settings. Thanks in advance!

My Iphone 4S is doing the same thing.. All of a sudden the WIFI button is gray and not working. I chatted online with a Rep. He had me call *228 and hit option 1, then call again and hit option 2. All of a sudden the WIFI button was black. But it could not find any network. I shut it off and restarted it and now button gray again. I called that number again and still gray. I read somewhere else that a lot of people have a problem with the WIFI button. They say it basically just stops working. This was a replacement phone because the volume stopped working on my original phone. I assume they gave me a refurbished one because it didn't seem new. I'm due an upgrade in 3 months. I'm disabled and just hate driving to the store again. I wish there was an easier way.

WiFi issues with Curve 8530

Hi,
I am having major WiFi issues with my Curve 8530. Everytime I connect to my wireless router, it takes a long time to connect to BIS, and then if I try to use basically any data at all, my router drops my Curve 8530. Sometimes it stays connected, but I cannot use App World at all, and email, and web browsing is all over the place in terms of speed, sometimes it is fast, while sometimes it is slow, and most of the time it stalls while loading a page. How do I configure my router for use with BIS and have it not drop my Curve 8530 everytime I use data over WiFi? BIS works perfectly over my cellular carriers network, so BIS is activated on my device. I have tried giving my BB a static IP, but that did not solve anything. My router is a Netgear WNR2000. Also, I have the latest device software installed on my BB, and all of my apps are up-to-date.

Hi,
Have you had any luck and resolving your problem?
We have a similar problem but it's with iOS devices where only one can connect at a time. We have about 10 that need to connect. All other laptops and tablets connect fine.
Power cycling the AX411 fixes it temporarly.

WiFi issue after 6.1.2 upgrade

I upgraded my OS to 6.1.2 and now I'm having troubles connecting to the internet at work. I did reset my network settings and inputted the appropriate password and still having issues. It identifies the network but when open safari or an app requiring internet connection it goes nowhere. Is anyone else having this issue. Does anyone know how to fix this problem. Keep in mind my connection works fine at home.

Yoga 11S WiFi issues

Hi all,
As with many I am experiencing severe Wifi issues with new Yoga 11s. I will try to explain in detail in the hope that someone who better understands how wifi really works might be able to help diagnose.
I have a Talktalk badged Huawei HG533 router. This delivers c.15Mbs reliably all around my house (2xTVs, computers up and downstairs, 2xphones). Using Speedtest.net to capture speeds.
With the Yoga, if I sit right next to the router (as I am now), I get 15Mbs. In other parts of the house I get just 0.5Mb, including rooms where other devices are measured at 15. I have updated drivers and upgraded to W8.1 though I experienced exactly the same problem before the upgrade.
I have tested every room and it seems that it will either work at very close to the maximum (in a few rooms) or drops off catastrophically to 0.5mb or less. There is no in between. I never lose connection altogether. There seems no correalation between the level of signal displayed (4 or 5 bars) and the speed.The 'good' rooms are separated by fewer walls.
I have also observed that on occasion having tested in a good room and then moving to one of the bad rooms it initially shows good performance, before seemingly recognising where it is and throttling back to unusable.
It is as though once it gets to a certain distance/separation/signal strength it somehow 'jams' the signal.
I really neeed to find a solution to this as 1. my office is one of the bad rooms and 2. I am often in hotels, airports etc and need reliable internet even in poor signal areas. Any help much appreciated.

Hey everyone, I just registered here and I couldn't find a solution. Apologies if this has been covered already.
I received the Yoga 11s i5 as part of an internship and after keeping the package under wraps for a month or two, I decided to give it a go and start using it instead of my Microsoft Surface. Everything works smooth and I love it to bits - except for the WiFi.
I was able to connect a few times, but for the most part it just doesn't work. The WiFi icon in the bottom right corner displays the adapter icon with a little red x, and the Windows troubleshooter is unable to find a solution. I'm really not sure what the problem is because, so far, my connectivity problem is entirely random - several times, I was able to connect and use the WiFi regularly only to be greeted with the same problem next time I start using the computer. The troubleshooter once displayed an error message amongst the lines of "The network adapter is experiencing hardware/software difficulties".
I don't know if it is worth mentioning that I live on a college campus with a dodgy wifi connection, but every other device I ever used is working properly. Any suggestions? Only thing I did try so far is refreshing the system and reinstalling Windows but, to no avail.
Thanks in advance!
