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
Hope this resolves your random "limited connectivity" problem.

I can not join the my home WIFI network. I have iPhone and iTouch connected as well as my windows laptop. I have trie power on rese, and network reset. What do I do next?

This is something else you can try.
Go to Settings>WiFi>Your Network Name (tap the blue arrow)>Forget this Network. Reboot your iPad, hold down on the sleep button at the top for a couple of seconds until the red slider appears, slide to shut down. Then press the sleep button again until the Apple logo appears and let go of the button and the iPad will restart. Try to join your network again.

I don't know what's causing the problem.

Sounds like something is broken. Unfortunately, it's no longer eligible for a discounted out of warranty replacement. Find a competent repair shop or buy a new phone.

Is it disabled due to too many incorrect passcode attempts ? If it is then you may need to put the iPad into recovery mode : http://support.apple.com/kb/ht1808 - you should then be able to reset the iPad and restore/resync your content to it.

Lenovo G510 wifi problem (Solved?)

Hello, few days ago I bought the lenovo g510, which comes with Win8 x64.
The laptop works perfect except the wifi does not connect me to any network. When I try to connect it tells me the connection is limited or null
Looking in the device manager, my wifi seems to be:
PCI \ VEN_14E4 & DEV_4727 & REV_01 & SUBSYS_060914E4
Where I can get any driver to work properly?
thank you very much
SOLUTION?:
I think I've found a solution (a workaround) ...
For next wifi card:
PCI \ VEN_14E4 & DEV_4727 & REV_01 & SUBSYS_060914E4
"Broadcom 802.11n net adapter" <- This can be different
Driver: 6.30.223.143
Date: 06/08/2013
OS: Windows 8 x64
In the device manager, right button and click on wifi device Propierties -> Advanced options -> WMM -> Disabled
This will force the card to work in g mode (54mbpps), but at least it connect and dont disconnect with the time...
Solved!
Go to Solution.

Going through the device manager worked for me too, FINALLY!
Been spending the last week since I bought my G510 to get the wifi to work for more then 5 minutes, and this was it.
Thank you very much my friend.

Lenovo G505s wifi slow afrter upgrading to SSD

Hi,
I have Lenovo G505 (59-380146) (APU Quad Core A10-5750 2.5 Ghz/ 6GB Ram) Windows 7 x64. Upgraded my HDD to SSD (Sandisk SDSSDHP256G FW:X2316RL).System become rapid speed, windows boots in 8-10secs, HD tune transfer rate is between 357.3 and 409.6 MB/sec, simply everything just went perfect except Internet speed... With old HDD it used to be around 36-40Mbps, with SSD its now only around 11-13Mbps... My wireless card is Atheros AR956x. Drivers are up to date and downloaded from Lenovo support website. Tried old HDD - wifi works perfect.
Does anyone knows whats the problem and how to fix it?? I only write here because I tried everything...
Solved!
Go to Solution.

hi Tomas985
Welcome to the Lenovo Forums.
Just to check, when you open Device Manager > Network Adapters > Atheros AR956x (properties) > Driver Tab, have you tried comparing the wireless driver version from the old HDD to the new one?
If the drivers are different (it will help if you can list them here) try to re-install the Wireless Driver from the lenovo website or from the D:\Drivers\WLAN folder (old HDD) and ensure that the driver version is:
Atheros v10.0.0.242 (Windows 8)
Atheros v10.0.0.263 (Windows 8.1).
If the drivers are the same and you have installed a firewall or security software (eg. Norton, Mcafee, AVG Security Suite, Zone Alarm, etc.), try to temporarily disable or uninstall them and observe.
Alternatively, try also these drivers:
- win8-v10.0.0.287-whql.zip
- Win8x64_6.30.95.29_WHQL.exe
Let me know how it goes.

Dual Band (5ghz and 2.4 ghz) Wireless Network Config and Dropped Connection

Hi, I have an Airport Extreme (802.11N) and a Motorola WR850G (802.11A/B/G) that I'm trying to connect in a dual band setup - but something in my setup is causing the Airport to drop it's connection (before the connection is dropped - everything works great). After I lose connectivity, both routers show up in my list of wireless networks, the light stays green, but I don't have local or internet access. When I try to reconnect, the log on times out. Also, the Airport isn't displayed in the Airport Utility (light is green on the airport itself though). Unplugging and resetting the Airport Allows all computers on the network to connect locally and to the internet for a few hours until the connection drops again. While it is up and running, I have no problems streaming movies off the connected Airdisk, navigating the internet, and connecting both N and G devices to the network.
I'd love to hear from you if you've gotten a similar setup to work, and if possible, have you provide the settings you used to make this work. I've looked around quite a bit and haven't seen a detailed description of the process (even from the Apple documentation). Also, advice from anyone would be greatly appreciated since my wireless networking knowledge is pretty basic.
My configuration:
Time Warner cable modem connected to the Airport's WAN port. WR850G connected by LAN port to Airport's LAN port. Bridge Mode check box selected on WR850G. Airport setup for 802.11n (5Ghz). Unique SSIDs to determine which network is 'N'. Same password for both networks. My Firmware and utilities are up to date.
Computers/Devices on Network:
Two Macs with Airport Extreme N cards. A Vista PC with a D-link N card (only compatible with 2.4 Ghz so it connects to the G network). A Vista PC with a GB ethernet card connected to the Airport Extreme. Various other G devices like iPod touches and an old iBook. Airdisk connected to the Airport Extreme.
Thanks,

I removed the second router (Moto wr850g) and everything seems to be working smoothly. It must be some settings on that one that are causing the problem, but I haven't been able to get it configured correctly. I noticed there were some IP conflicts with my wireless wanting to use the old Moto router IP and trying to assign my Mac an IP from that router. Does anyone know specifically what needs to be disabled on a router in bridge mode? Since I have a third party router there aren't any handy wizards that can configure it for me.
Thanks again

Secure Connection-random pickup and drop

I am using a linksys SRX router running WPA personal encryption and my SSID is not broadcast. There is one windows desktop and 2 mac laptops on my network, all connect wireless.
Now for my problem...
On starting up my laptop it will normally find my network and connect no problem. When I close the lid (putting it in sleep) and re-open it about 50% of the time it will NOT automatically connect to the network.
A couple of strange things:
1) The problem seems to be getting progressively worse(My MBP is only 2 1/2 weeks old). The first 4-5 days I had no problems at all. Once it started happening it seems to be more frequent as time continues.
2) When the problem first happened simply turning the laptops airport off then on fixed the problem.
That stopped working and I had to add another step in the process by clicking on my wireless icon and selecting my network. (even though it already was checked)
Now if that simply fixed it I would not be so bothered, unfortunately that method of 'fixing' it stopped working tonight.
When I tried to use my normal 'method' tonight, my network name was no longer in the drop down menu.
I then selected 'Open Internet Connection...' in the menu and configured my network. This still was not fixing the problem.
So i go into the 'network' tab and 'configure', and my network is the first in the default network section.
The only thing that seems to 'fix' the problem now is to click on the 'assist me' tab and run 'diagnostics'. When i do this, it prompts me for my network info and then connects immediately once its entered.
Sorry for the extra long post I was trying to explain the problem and how i currently 'fix it' as thoroughly as possible.
quick recap- when i close my lid and open it up my laptop only connects to my network half the time. On startup it connects 80% of the time.
The 'fix' for me to connect has gotten longer and more complicated....please help me
MBP, 2.33ghz Core2Duo Mac OS X (10.4.8) also runs windows

Does'nt seem to matter what router you have, because Apple blame every body else's equipment - this is their advise:
Mac OS X 10.4.8: Intel-based Mac can't obtain IP address from third-party wireless router
Symptom or Issue
After installing the Mac OS X 10.4.8 update, Intel-based Macintosh computers may not be able to obtain IP addresses from some third party wireless routers.
In this event, the Mac is generally able to associate with the wireless network, but it will obtain a self-assigned IP address (169.254.x.x) and will not be able to connect to the Internet.
Products affected
Mac OS X 10.4.8
All Macintosh computers
Solution
Turn the wireless router off and back on.
Note: This step will disconnect any clients currently connected to the wireless network provided by this router.
If restarting the router does not resolve the issue, contact the manufacturer of the third-party wireless router to resolve this issue.
The last sentence says it all - its somebody else's problem!
My MBP C2 does the same!!
All my other Mac work perfect with Netgear DG834G, My MBP C2 does not, so it seems to me its the Apple MBP C2 that has the problem not third party equipment - so Apple get your finger out and solve the problem.....

Wifi problem: signal keeps going on and off and on and off.

For some reason the wifi indicator keeps changing from max strength to flat out no connection, max strength again, no connection, max strength, no connection... it keeps flipping back and forth. Not sure why this is happening because my other macs in the house (G5 and macbook pro) are showing a steady wifi signal.. so there is nothing wrong with my wifi router.
Any ideas how I can fix this?

Some steps to try:
1. Turn Airport off and back on, see if that stabilizes it. Or restart and see if it persists.
2. Create a new location in System Prefs->Network, and see if it still happens.
3. Unplug and replug your modem and router (let them sit for ten seconds) to reset them, just to be sure.
4. Go to a wireless hotspot--local coffee shop or library or something--and see if it happens.
If after all that, you're still seeing the issue on multiple networks and multiple set-ups with your machine, then it may be your card and it's worth a call to AppleCare or a visit to the Genius Bar.

Slow and dropping connection WRT300n v 2/WMP300 v 2

Slow an dropping connections on WRT300n v 2/WMP300 v 2 updated with latest firmware/driver.
Before update it gave a speed of 3-4 mbit/s and after update about 30 mbit/s, this is just a bit better(10-13%) than the D-link products (604/AP2000+/DWL-G510) i intended too let go of old age.
For E-mail and surfing the web this speed is ok, but sharing files and use a mediacenter its not ok.
Next problem is that after about 30-40 min of full load the router just dropps all connections and reboots or what ever.
The Linksys products WRT300N/WMP300 is not a what a expected it too be

Slow internet speeds and dropping connection

hello, I am making this post on behalf of my dad, for a good few months (5-6 maybe even longer) we have been experiencing slow internet speeds and a dropping connection when ever the phone is picked up. when an incoming call is answered some or all devices connected to the internet drop out for a second then come back online, the connection does not completly disapear but causes any voice chat, streaming or gaming to disconect. We have BT wireless phones (not sure what exact type) which we have had for a few years. they are connected through an ADSL filter which as far i can remember has been there for years. We have a netgear DG834GT router which has also been there for a few years. I went onto its settings and got this information, not sure if its usefull or not.

Wifi Problem - can't get iPod Touch to connect to Internet

I've seen lots of posts and discussions around this issue but cannot seem to nail down a solution. I have no security or encryption whatsoever with my wireless router & network. Other devices can connect wirelessly with no problem but my iPod Touch, although it shows that it is connected to my wireless network with all the proper DNS settings, it cannot access the internet. Of course, none of the wifi-based apps will work as a result.
Based on what I've deduced so far, I think the issue is that my brand new iPod Touch does not like my older Linksys WRK54G wireless router. That said, my brother's newer iPhone picked up my wireless network fine recently??
Does anyone have any advice? Thanks.

I have read all the posts and did all the numerous solutions/suggestions for 2 days now and what worked for me is this:
I went to Dlink online and went to Wireless connection settings to change the SSID name as if I am using my router for the first time, then changed it to WPA 20 characters! then saved the settings. Do this on the original PC (in my case, a desktop linked to the router via Ethernet cable as I have 2 laptops running
from that router as well. Note, before doing the "Save the settings"
above, I reset the Dlink router (by putting a pin at the back of the unit,
then turning it off and on including my separate Netcomm modem.
You then go back to your Ipod touch/ Settings and Choose the new Network Name.GOOD LUCK.

Wifi problem with repeaters - there was an error connecting

so I'm repeating a motorola gateway's wifi signal with a belkin f5d7132..
with the repeater on .. opperating. and doing its range extending magic, my pc can connect to the network, but my mac throws up an "error connecting to network" message.. "trying again" gets me nowhere.
unplugging the repeater fixes the mac up nicely... it's able to connect directly to the motorola gateway..
when I look at all the wifi connections. it show two instances of the "repeated" signal... two "ian" ssids.. I wonder if this duplicity is messing things up for me and my macbooks attempt at connecting to the repeated wifi.. I linked to a couple screen captures of my motorola and belkin config pages..
the one thing that surprises me, is that the belikin router doesn't have an "entry" in the motorola DHCP list.. I'd think the belkin repeater would have to lease an IP address from the motorola, and that lease would be noted in the motorola's dhcp table.. I'm sure there are different schems for repeating..
anybody successed with this belkin in a mac / pc cross platform environment? any magic settings that I'm missing?
here are links to those two screen captures

Ok. Got it fixed.
For a real fix:
Try trashing the ~/Library/Application Support/Apple/AirPort folder. This should solve the problem this time and next time.
If you are reluctant to do that, log into your 'test' account. (You do have a test account, don't you?)
Do the update from there.
Apparently we have something corrupted in our support directories for the AirPort device.
I first fixed my problem by doing the alternate log in method and found that all 3 of my devices were needing a firmware update but only the Capsule was reporting an update within my own account.
