G580 Wifi problem

I'm using lenovo G580(20157) wireless is connected to wifi network sometimes it disconnected automatically and shows no internet access while disconnecting and connecting to particular wifi network shows internet access but sometimes without system restart I'm unable to use internet.
I have installed updated drivers and it's in warranty period.

G580 WIFI Problem ONLY at school (redirected website for wifi password)

Hi all,
I recently purchased a lenovo G580 laptop; windows 8
My laptop wifi works perfectly when I am at home or connected to any normal wifi.
It does not work when I am at school which typically once you connect to the school's wifi, it opens up a web broweser asking for your usename and password to get compelte access. (figure 1- from my other laptop)
My lenovo laptop cannot download this website, therefore I have no internet access at school since I cannot put my information inside. (figure 2- from lenovo laptop)
The problem is not my school's router because I have wifi connection on my other laptop here without any problems. Also the problem is not really the location/wifi of my lenova laptop because I can connect to my phone's personal hotspot when I am at school.
Simply, the problem is found when I cannot connect to my school's wifi because it requires me to download a site to put my information.
I have read other forums and try to figure it myself, however, I am very noobie when it comes to computers. So I appreciate a step-by-step instructions. For example, please provide links that I may need to download to update my driver.
I have called customer care, and I am not going to pay 100 bucks just to fix a simple problem. So i appreciate your time.

check whether you have set up your wifi settings correctly.(i mean 'servers' and login credentials ).

Lenovo g580 Wifi new problem broadcom bcm943142hm

So week like week ago my wifi problem started the signal strat to be very low (0) or full but for like a second.
I have tried change plugs(black goes first then white?) /new drivers/change to simple broadcom to network adapter I even tried to unplug a whole card and replug it. I also tried things like Broadcom 802.11 Multiband Network Adapter but still no luck. I forgot to mention that it connects with phones with no problems and other devices connect with router without any problem so as my Lenovo not so long ago
Windows 8.1

If I understand correcly - you are getting low WiFi signal strength from your wireless adapter. Have you attempted connections with other WiFi hot spots or access points to eleminate issues with your own wireless equipment?
If you have a local wireless hotspot (internet cafe) that you can try, do so. If your wireless remains with very low (one or two bars) at all WiFi spots you try, then it would sound like your WiFi card is begining to fail. If you decide to replace the WiFi card, make sure you use one that is Lenovo branded or it will not work.
Good luck.

Strange wifi problem on a brand-new MacBook Pro

Hey there, I'm new here. Desperation has got the better of me, and I hope I can get some advice.
So, last sunday I bought a brand new 13" MacBookPro with 2.8g i7 processor and 10.7.2 OS (I can't update to 10.7.4 because System Update tells me the download has been tampered with or corrupted after I waited 2 hours for it to finish, but I'm trying a direct download from the website). Here's the exact product: http://www.amazon.com/Apple-MacBook-MD314LL-13-3-Inch-VERSION/dp/B005CWIZ4O/ref= sr_1_5?ie=UTF8&qid=1340301247&sr=8-5&keywords=macbook+pro+13
Everything is all perfect except for a strange wifi problem. Note that the wifi does not turn-on or off, it doesn't disconnect after 'sleep', it doesn't get less speed, it doesn't constantly leave a preferred connection (once I chose my home wifi it always connects to it no problem). The wifi bar is always full. What is wrong is that the internet is kinda 'glitchy'. The best metaphor I can think of is that it's like a car that has to be pushed down the road before the engine can start. Please, bear with me because this is kinda hard to explain and I'm not good at tech lingos.
One of the symptoms is browsing can get really slow and inconsistent, almost as if the wifi gets turned off in the middle of browsing. For example: if I look something up on Google and then open 5 new tabs, probably only 2 or 3 of those tabs will eventually load while the other two will not get past the long 'http:.......google.....etc etc' address and will eventually show one of those 'error loading page because there's no Internet connection' notice. This happens a lot. Sometimes I have to refresh/retry loading a page a couple of times before it finally loads, then usually everything will get back to normal and I will be able to open multiple tabs with no problem, but in a couple of minutes I would try to open another site and the problem will start again.
So I tried to see how it does with downloading using iGetter. Fortunately I also have a Macbook (white-plastic casing one) and my brother has an old 2006 MacbookPro so I can compare. With those two older Apples iGetter starts receiving data in less than 8 seconds after I click Start, while my brand-new Macbook Pro can take up to 15-20 seconds, sometimes it doesn't even start at all and I have to re-click the start button. But once the download actually starts (on my new MacBook Pro), it downloads like normal, it doesn't stop and the speed is also as good as I can get. Strange huh? Hence, like a car that has to be pushed before the engine starts.
I also tried 'speed testing' from a website with all 3 laptops. On my old MacBook and my brother's MacBook pro, once I click 'begin test' it takes only a couple of seconds of 'ping' before the download/upload speed measurements start, but with my new MacBook Pro (just like with iGetter) it takes up to almost a minute before the measurements start, sometimes it won't start at all and I have to re-start the test.
Well, thanks for reading. And hope you can help me shed some light into this. Because it is really preventing me from really enjoying my new MacBook Pro. And if this is most likely a hardware problem, I'd better get back to the store and try to get it replace or something while it's only been 5 days. *cheers*

Hey guys.. Thanks for the replies. Unfortunately, I bought the MacBook in Indonesia where there are no such thing as an AppleCare. The only option is to leave the Apple product to one of the 'Authorized Apple care centre' and have whoever do whatever to it without guarantee of success. As for returning it and getting a brand new one, I also don't know if there is such a deal here, but that's actually a good idea, will try to go to the store tomorrow. Although, I'm worried that the problem might be with OSX Lion or something and getting a new one won't help.
mark75090, I've tried resetting the router when I first noticed te problem, didn't work though. I've checked my new MacBook's wi-fi (option+click wifi bar) and it says 'PHY Mode: 802.11g', so does my MacBook and the old MacBook Pro. I don't know what those mean though, and I don't know whether or not my router is an N., can you tell me more please.. I have tried with the other two turned off, and only the new MacBook using the wi-fi but the problem persists. I have also tried connecting directly to the router, but as I described, the problem is too subtle for me to notice the difference.
Also, if I create a brand new Wi-Fi connection in network preferences and connect to my router through the new Wi-Fi profile, the problem seems to be gone for an hour or so, then it always comes back though. I have also just finally installed 10.7.4, but it doesn't help either.

Wifi problems still exists?

I sold my gs60 that had an 870m back in january mainly because i couldnt bare the wifi problem. I really loved the laptop and everything about it but everytime my laptop overheated the wifi would drop from 100mb to 1mb or less at times, monday im thinking of buying a new msi laptop and im wondering if these models that are currently being sold on amazon and etc still have the wifi problem or has it been fixed?
And trust me, i read the forums, i read the guides and im pretty decent with computers/software and etc, i uninstalled, reinstalled, updated it, changes adv. settings and even though it improves certain things the problem was still there. So does it still exist?
Or should i just buy a USB wifi?

This problem only occurs in earlier patches of Intel WiFi card of GS60 2Px (8xx series of NVIDIA graphic cards) and not every unit was affected.
If you don't want to take this risk, I'll suggest you buy GS60 2Qx (9xx series of NVIDIA graphic cards).
USB WiFi is a good idea. It certainly has a better signal comparing to the WiFi embedded in the body of the laptop.

Macbook pro 15 inch wifi problem (late 2011)

Hello,
Here I write a little desperate with this problem that I have on the MacBook Pro (late 2011) with WIFI .
For several months ago, when I power on the MBP is all apparently normal , spend a few minutes and I lose the WIFI , the icon still comes out as "connected " but no WIRELESS signal , I turned off the WIFI, but, when I try to change back to turn ON, the icon of WIFI still OFF ( the inverted triangle ) . Restarting the MBP and still the problem no signal and appears as disabled , delete PRAM several times until finally everything works again , spend some time and again the same thing sometimes is fine for several hours, go out to eat and return and again the same thing, the worst was when I saw the message "Hardware not found" and "X " where the icon goes WIFI . I rebooted several times and not managed , this was the "hardware not found" message. Some time ago I went something like , when Lion had and read that resetting the PRAM and managed , never came out , but now even that it manages , and it is becoming more common , I thought it was the OS ( MacOSX Mavericks ) so I reinstalled (I'm not used Time Machine, I install all again ), this work the lasted several days without fail, until she passed again, I'm out of WiFi, when I see no WIFI signal in the list , restart me WIFI goes off and I can not change , restart it goes back to " hardware not found" and so on.
Now desperate for this, I opened the MBP , disconnected the cables from the Airport card and reconnected with care and making sure you are all well , turned on the MBP again and works!!, I lasted two weeks , then I thought it was that. But again the whole problem again.
Already investigating more online and I found some details from other users
1 / Both WIFI and Bluetooth are on the same card ( the q disconnected and reconnected )
2 / If the card was wrong , losing the WIFI Bluetooth should lose , but I tried Bluetooth and has no problems
3 / Reported that resetting PRAM or SMC but still, in my case, does not work.
Now all I have left to rule is the WIFI antenna that is located ( if I remember correctly ) for the bottom of the screen, and according to several users this tends to fail from constant use to close or open the MBP (or either to cover or uncover ) , and sometimes it just heats and heats close to this area .
Has anyone had a similar problem? My MBP turns 2 only on March 7, 2014 , I can not believe all that cost me and now is about to fail , I have a Sony VAIO Core 2 Duo for about 5 years (or more) ago and is still running and has been dropped many times and nothing has ever happened : (
Additional data on my MBP ,
Several months ago ( long before the problem with the WIFI) I changed the hard drive for an SSD ( 250GB Corsair Neutron X ) .
There is a problem that often makes me too, is that when you close the MBP ( to open ) , and open it back again ( out of sleep) the following happens :
1 / It instantly freezes when waking from sleep and I have a long wait to enter the password.
2 / When you leave idle normal let me put the password, but just when giving ENTER freezes
3 / Out of sleep, let me put the key, ENTER and when I load the desktop freezes
Another problem :
This only happened to me a few times , as I mentioned , my MBP is formatted ( have Mavericks ) before formatted (clean install without time machine) , I closed the MBP ( I sent to sleep) and the open the screen was black , but as with bright, and not leave the state, turned off force ( pressing the button) , start the MBP again (power on) charged normal gray screen with apple but with a fairly low brightness, spent a few seconds and turned the brightness to normal and started normally .
I hope some can help me with these problems.
PD : I'm from Peru , if anyone knows a trusted service that please let me know .
Thank you very much .

Your wifi problem sounds very much like the problem I had. The wifi would drop out, the icon showed it was still connected. If I turned it off, I couldn't turn it back on. Another user here pointed me to the problem, which was the wifi cable (the flat cable goint from the card to the motherboard). I found it on ebay for $13 and it's been running fine since I replaced it. This is the repair guide for your machine. The part number will be on there if you click the link.

How come they still haven't fixed the ios 6 wifi problem on ios 6.0.1 making me mad -.-

I know apple or the tech support doesn't read this but come on tell them to fix the wifi problem that started from ios 6 and still continuing to ios 6.0.1. I already gave them another feedback like 5 days ago. I really don't want to reconnect to my wifi everytime. I already did everything possibly to fix my wifi problem. I know its IOS 6.0.1 because it started with ios 6 and still not fixed by apple update to 6.0.1.
I have a very limit data plan of 300 MB on at&t and I don't want to go over so I rely on my wifi most of the time.

Maybe you just lucked out but both my devices running ios 6.0.1 have wifi problems shutting of at random times during sleep. I know you guys will say when its plugged in it doesn't lose wifi true but I never remember having this problem in the previous ios verison from ios 4 to 5(On my Iphone 4, and from my Iphone 4s from IOS 5) until I updated both devices to ios 6 or even when I had a iTouch 3rd gen long time ago I never remember it shutting of my wifi. I am telling you this never happened before IOS 6 where I need to leave it plugged in just to have my wifi during wake up.

I thought I believed my iPhone 4 with iOS5.0 would not disconnect during sleep mode. However, I was wrong. What I did was to ping the IP addresses on my iPhone 4 (iOS5) and iPhone 5 (iOS 6 then, and iOS6.0.1 now) when they were in sleep mode. Very true that there were timed-out on both devices. Once I woke them up, ping went thru. I did a scan on my home network using my iPad while the other 2 phones were in sleep mode, I was not able to see them.
I thought my iPhone4 did not disconnect too. But again, I think the reconnecting to wifi on iOS 5 is SO MUCH quicker than on iOS6 so user would think there was never a disconnect.

Wifi problem after.4.3 update on xperia z

Hi all,
After updating my Xperia Z (C6603) to build number 10.4.1.B.0.101 I've been having connection issues with every Wi-Fi network.
I've checked the forum but I only found problems about people having Wi-Fi issues with their smartwatch, I do not own a smart watch this is just a general networking issues.
Here's the problem in detail:
When having no Wi-Fi switched on while booting the phone the phone will start without any issues, I will receive my 3G/4G signal and I can browse, e-mail, everything.
Once I switch on Wi-Fi it will start connecting to previously stored Wi-Fi access points but will not connect. Eventually it says that there was a problem with connecting, even though this will take several minutes.
I can go into the Wi-Fi settings, select a different Wi-Fi network (if it is in range) and press connect, however the settings app will freeze at that point and eventually I'll get a notification that the settings app has stopped working.
I have found a "work-around": I switch the Wi-Fi to on, power off the phone and power on again. Now the Wi-Fi connection immediately powers on without an issue once the phone has completely booted, it also will connect to the default Wi-Fi connection that is in range. A different issue appears however once I move out of Wi-Fi range, it will no longer pick up my 3G/4G signal. It is also impossible to switch off Wi-Fi or switch Wi-Fi network connections without rebooting the phone.
As I said before this happened to me after updating to version 10.4.1.B.0.101 after having it received through OTA update. I do not have root access on my phone either so this can't be it.
Is there anyone experiencing the same issues? Is this somehow related to the issues people are experiencing with their smart watch connections (as seen in this topic: http://talk.sonymobile.com/t5/Software-Updates/wifi-problem-after-4-3-update-on-xperia-z/td-p/490591...
If there's anyone who is experiencing the same issues, or has found a fix for this I'd gladly hear from you.
Regards,
Danny

Email and big wifi problems.

Email and big wifi problems.
Why does it take 6 minutes to send a photo attachment when my iphone 4 will do it in 30 to 40 seconds ?
Why will my email account be recognised and log on only half the time?
Why does the wifi keep dropping out?
Why does the speed and signal vary when I'm sitting two feet away from by wifi router?
All settings in my phone have been reset twice as per advice from vodapone

Thanks very much, jjgraphics. I will grit my teeth and try India once more, as you suggest, and then get in touch with the moderators.

If I install Yosemite and find that the wifi problems are too bad, can I go back to Mountain Lion?

Almost everything I do on my MacBookPro requires a steady wifi connection. I have been reading all the horror stories about the wifi problems with Yosemite. I would like to install Yosemite, but would like to be able to go back to Mountain Lion if the problems are as extreme as I have been hearing.
Details: My Mac is 3 years old (Apple Care ran out 2 days ago!). I recently upgraded from 4GB of ram to 16GB.
Router is a Linksys E4200.
I have an Iphone-4s
My husband has an older MacBook running Lion.
I connect to an Epson Artisan 835 with wifi via my router
We have no need to have the Apple devices communicate with each other.
I am currently running an appliance in Virtual Box. One reason I want to move to Yosemite is to be able to run it in VMware Fusion instead.
Thanks.

Hi there CarylLynne,
If you upgrade to Yosemite, you should be able to use the following article to revert to the previously installed OS using Time Machine, named:
OS X Yosemite: Revert to a previous OS X version
Thank you for using Apple Support Communities.
Take care,
Sterling

Wifi problems with new ipad

I'm trying to learn how to correct wifi problems with new iPad. It is the wifi only, 64GB model. I want to be able to use it at work, where we have a great wifi network. I can usually connect to our network with no problem, but after an hour or so my iPad loses the network. When I try to reconnect, I see that the network is showing full strength reception, but I get the error message from the iPad that I am "Unable to join" the network. My iPhone connects to the same network seamlessly, as do all of the other iPhones of my co-workers and the older generation iPads that some of our staff has.
At other locations, I typically have no problems (home, apple store, etc.) but I have had the same situation pop up at a coffee shop where I could see that there was a wifi network available, but I could not join it even though it was the shop's free wifi.
I have tried turning the iPad off, turning off wifi and turning it back on again, and forgetting the wifi network in question. I can't think of any other methods that are available to an end user to correct the problem.
I have already gone to the Apple store to swap out the unit, and the newer one is having the same symptoms.
Can anyone offer any advice here? This is quite frustrating.

No problem! Have a read at this most interesting article which has special significance as regards your models!

IPad mini retina. After upgrade to iOS 8 and after to 8.0.2 I can't use my iPad because of wifi problem!

After upgrade to iOS 8 and after to 8.0.2 I can't use my iPad because of wifi problem

I am having a similar experience. Since upgrading my Ipad 2 to iOS 8 and then iOS 8.0.2 I have not been able to use wifi consistently and it is very frustrating. I can no longer watch any video because the wifi shuts down and won't come back without a complete reboot of the iPad. And forget about consistent bluetooth! My ipad worked perfect before the "upgrade" to iOS 8 and beyond but now it is really worthless. I have spent a lot of time and have tried every fix that I have read about online and NOTHING has corrected the problems created by the upgrade. After spending a lot of time trying to resolve this I am certain the problem is the buggy "upgrade" but I feel like no one at Apple is listening. I have always loved Apple products but this rotten Apple experience is making me think about exploring what else is out there. Apple folks, I recommend getting this fixed quick or your stockholders won't be smiling!

Still on 10.6.5 but having wifi problems with Canon MP495

At least I think it is a wifi problem? Love this printer - worked brilliantly since I have had it and not had any issues with it at all once installed properly. However, over the past 3/4 weeks I keep getting communication problems and the wifi button/light flashes during printing and more often than not the printing stops and spits out the paper with only a few lines printed. I then have to pause the printer and resend several times - and I'd be lucky to get a complete print without error 1 out of 5 times. I have not changed position of the printer. The kids laptops with windows 7 did not appear to have this problem until first thing this morning when my daughter needed to print something for school on 'special paper' and guess what - it stopped and spat it out half way through! Any clues as to what to do wold be very much appreciated.

Stressed Mum wrote:
I have moved the printer as the signal was low - 38% and link 36%. It has increased slightly up to 48% but that is on the dining room table now Why would the signal change? It used to communicate without any problems at all - this is very disappointing.
There can be a number of reasons why the change has occurred but the most common is other wireless devices causing interference, and not just from your house. If a neighbour is using a wireless router on the same channel as yours then this can cause interference. A quick fix can sometimes come from turning off the wireless router for a minute and then back on. Many routers will check what wireless channels are being used and select one that is not being used by another router within range. If the router cannot do this automatically then a manual setting of a channel can help.
There are some utilities that can scan your premises for all wireless signals. This can assist with locating an unused channel. The following is an app that I have used for helping friends with wireless issues.
http://www.macupdate.com/app/mac/27740/airradar
Can I confirm that it is actually linking with the pc/mac that sends the print and not the router?
The printer should be linking to the wireless router and the computers should also link to the same router. The printer does not support a direct connection to it from a wireless computer.
I really do not want to have to move the printer every time I/the kids need to use it. I think I'll update to 10.6.6 just to see if that makes a difference and revert soon.
I don't believe the 10.6.6 will resolve this. And you also said that the Win7 computer also had problems so it would suggest there is more of a problem with the connection from the router to the printer.

10.6.8 and Lion wifi problem

hello,
I am trying to use my mac for one week...... ;(
everything was fine until update to 10.6.8... wifi problem as many of you already know. tried to update to lion, same problem. Got back to 10.6 and then update to 10.6.8 using software update... then formatted again, fresh install 10.6 update to 10.6.8 using combo update, same problem.
tried to delete firewall file, turned off ipv6, changed security of my router from wpa2 to wpa, tried different channels, reset SMC and RAM, all the solutions we can research... all the same
now I am on 10.6.7 and seems i still has the problem happening....
hello apple, more than a month and no solution yet????
I've read somewhere a new procedure that consists in update to 10.6.8 and before restart do some procedures.... but I can't find it anymore, any help?
I guess that solution is the only one remaining I did not try yet.
thanks and regards,
raul

well, it's caused by software only, there is nothing wrong with airport hardware
hard to believe, it's like windows old time sake, loosing precious days fighting with a computer...
too bad apple
