Yoga 11S WiFi issues

2013-10-29, 10:47 AM

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.

Re: Yoga 11S WiFi issues

I notice that 80 people have viewed my previous post but no one yet replied :(. Thought I'd give an update to see whether anyone else experienced similar problems.

 

So - machine still behaving as before (good or bad, nothing between) so I bought a USB wi-fi adapter because I needed to get connection in my office.

 

I got exactly the same issues! :(.

 

Sitting in my office - old laptop (shortly to return to ex employer) running along nicely at 15Mbps - new Yoga, with TP-Link adapter in (and on-board RealTek disabled) crawling at 0.3Mbs 2 feet away.

 

Could it be some on-board interference coming from Yoga itself (that takes over at a certain level of signal)? Could it be something to do with W8?

 

I am at a complete loss and would really welcome any feedback or suggestions from other forum members.

 

Many thanks

Yoga 11s - WiFi issue!

2014-04-02, 18:55 PM

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!

Similar issue with poor wifi connectivity with Yoga 11 (8.1) Realtek RTL8723 adapter. Many times will show all 5 bars on the wireless icon, but there is no Internet connection. Clicking on the solve problems says there are no problems detected. ALso there are no connections available -- however all of my other devices are connected just fine. The only solution has been to reboot - but that seems to be an inappropriate solution. Ideas from others or Lenovo?

Lenovo Yoga 11s Connection problem

2014-10-09, 3:20 AM

Hello there,

   I have a Lenovo yoga 11s that was working fine for a while. When on one day, the wifi stopped working. It says i am still connected but i cant get on anything on my desktop. Any apps on my start menu are okay like google seard (im running 8.1) but when i open up explorer, minecraft, or chrome, it says it cannot connct to the internet. The wierd thing is that all the other electronics at my house work, it's just my yoga. Can you help me with that, Thanks!!!:smileyhappy:
