Wifi connection slow on Lenovo Twist s230u

Hello!
For the first time in my life I am posting my own problem to a forum, after three days of almost no sleep, trying to fix this problem.
No matter on what Wifi network, the internet speed tested in a few speed testing sites never passes 0.4 Kbp/s.
I have seen endless threads, videos, discussions, and tried every solution offered.
Non of them discussed the Wifi adapter I have.
I have even re-installed Win 8.1, with no success of fixing it.
These are my specs:
Windows 8.1 (x64) (build 9600)
LENOVO 33474HU ThinkPad Twist
Main Circuit Board: LENOVO 33474HU Win8 STD DPK TPG
Communications: Broadcom: 2x2 11a/b/g/n Wireless LAN PCI Express Half Mini Card Adapter
Please! Help!
Eitan.
Solved!

So, about a week ago my macbook pro started having lots of issues: wifi connectivity, slow performance, sound issues, spotlight wasn't working. After going through the issues with apple support, they decided the best course of action was to erase the hard drive and do a reinstall. Since I have a recent backup this seemed like a good enough option. They were kind enough to send me a copy of the snow leopard disk to do the install since we couldn't get it to complete through the disk utility. Not sure why, since it says we are fully connected, it just never completed.
Anyway, so now that you have the background here is the new issue. The macbook pro keeps spitting out the disk I'm trying to install from. Disk utility and using the 'Startup Disk' function from the apple menu doesn't read the disk.
Can anyone suggest a solution to this vexing problem?
Thanks in advance.

Jeremy.Laurin,

Default Partitions for lenovo Twist s230u

Hello,
I have a Lenovo Twist (s230u) and need to do a system recovery. Unfortunately, neither the F11 option is working nor recovering from win 8 itself. I do not have a win8 disk (wasn't supply with the computer) !
The only option I guess is to get a win8 drive and do a clean install. Before I do this and reformat the drive, can someone tell me what to do with the different partition on the HDD and the SDD ? I see the disk is divided into multiple partitions... Even if I do a clean win 8 installation, what should I do about the 260 Mb, 1000Mb and 7 Gb partitions (EFI, recovery and recovery respectively) Are they necessary ?
What about the SSD ? Technically I guess since it is separated, it shouldn't affected.
Thank you
Cyril

Hello and welcome,
Easiest - if your drive stays alive long enough - is to make a recovery flash drive and use that to restore to a new drive.
Methodology to create Recovery Media and reload a Lenovo system with Microsoft Windows 8 preload
If you have a MS Win 8 install DVD of the matching version you can just copy the contents to a FAT32-formatted flash drive and use that for a clean install. The license is in BIOS and shoud be picked up. (CAVEAT: I've done installs from flash, but not verified that the license is picked up.)
Note that the copy-to-flash install works for MS media but not for Lenovo recovery DVDs.
Worst case: use a USB DVD drive. Worst, worst case: purchase recovery DVDs from Lenovo support _and_ use an external drive.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

IPad mini wifi connection slow

I just got an iPad mini, and i have noticed that the wifi connection is so slow. I have many other devices, and the wifi on them is great. I've updated to ios 6.0.2 but it hasn't helped. Is anyone else experiencing this? Can it be fixed? Thanks

Expresscache on Lenovo Twist s230u

Hello,
After installing latest drivers for Expresscache (1.3.110.0) for Twist s230u, Expresscache stopped working. "eccmd -info" command outputs "Failed to retrieve product license". Restarting service, re-installing didn't help. Does anybody have similar issues? What is possible to do to resolve them? Thank you.

So, that's what staff at Condusiv.com (devs. of Expresscache) replied about latest installed drivers of Expresscache, downloaded from Lenovo:
"It appears that the version of ExpressCache is not an Lenovo specific application. Please contact Lenovo Support and obtain a Lenovo specific version of ExpressCache. The application will check the BIOS string for the specific manufacturer prior to enabling the product."
Anybody can help? Thank you!

Wifi connection slow after streaming, Apple support couldn't help

I have since quite a while problems with my internet connection. I tried it in several countries, but always the same: As soon as I stream something or open to many browser tabs, my wifi-connection becomes terrible and stays terrible. It's definitly dependent on how I use the internet. If I open 3 youtube videos or the top10 Google search results, my wifi connection becomes bad. My Speed drops to lower than 1Mbit, but lots of timeouts. After a while it works again.
What I already tried:
-Reinstalling MacOS
-Installing windows (same problems with windows)
-Resetting SCM
-creating new wifi environments
-putting MTU to 1453
-clear DHCP
-deleting some files in the library for resetting connections
-clearing browser cache
-testing with Safari and Chrome
-disableing bluetooth
Now I bought a CSL Wlan Stick but there are not mac drivers out there and I don't have a CD-Drive for installing the drivers.
What can I do?

The only possible way that you can restore the data is by restoring the iPad from a backup. Did you restore from a backup at the end of the restoring process?
Why was Apple support not able to help? Is the backup gone?

Macbook Pro WIFI connection slow and intermittent

I recently moved to a new apartment and had Time Warner install our internet/Wifi. My Macbook Pro will connect to the Wifi and work fine for about 30-60 seconds and then become extremely slow, even to the point of no connection most times. I have tried using both the new router and the old router that worked just fine at our old apartment but both behave the same way. I have reset the routers multiple times but that does not fix the situation and I do not believe the router is the problem since my two roommates (one of which uses a Macbook Pro) have no connection problem. My iPhone connects perfectly fine as well. When I am on other Wifi addresses, my Macbook works just fine. Also, my Macbook is only one month old. I called Apple to try and solve the problem and they believe it is an interference problem however the connection remains the same no matter how close or far from the router I am and all other devices don't seem to have interference problems. Any help is very much appreciated!

Might be corrupted network preferences ..
Type or copy paste the following:
/Library/Preferences/SystemConfiguration
Click Go then move all the files in the SystemConfiguration folder to the Trash.
See if that makes a difference.
Your Mac will generate a new SystemConfiguration folder for you.
If that doesn't help, try Wi-Fi diagnostics here > Wi-Fi: How to troubleshoot Wi-Fi connectivity

IPad ~ WiFi Connection Slow as Death Itself

Title says it all...
My iPad is sitting on my desk; the wifi router is directly underneath it.
I try to load pages and it just hangs and hangs; the blue progress bar creeps across the screen.
Any ideas?
tyvm

At your convenience, goto the app store and download speedtest. This will give you some hard numbers about your connection. There are a lot of cogs in the process, and you need to try and figure out where the glitch is.
If your connection is slow, try a different router channel, or flip g and n and see it it works better. Take your pad to a different wifi spot and see if the speed is better there. Is your isp playing eith their throttle?
Lastly, sometimes the app store gets real busy, and things just slow down. For comparison, on a good clean wifi signsl, my pad measures out between 15 and 20 mpbs. On a weekday evening, during prime time, using my calble provider, i max out around 2 mbps. Sometimes less.

Iphone Wifi connection slow?

I have an iPhone 4s on 5.0.1 OS
Some reason, on Wifi youtube runs insanly slow. On 3G it is fine. I have never had any issues with my past phones or computers with slow connections on my wifi. I just got this phone 4 days ago. I'm already missing my android

Simple, try another network, like free Starbucks. And if iphone works fine blame your network. And if not get back to us and we ll start blaming your network together. Step by step starting with iphone.

Any help
Dr.Anand

Please answer as many of the following questions as you can. You may already have answered some of them; in that case, there's no need to repeat the answers.
Restart the router and the broadband device, if they're separate. Any change?
Run Software Update and install all available updates for OS X or the computer's firmware. Any change?
If possible, connect to the router with an Ethernet cable and turn off Wi-Fi. Any difference?
Are any other devices on the network, and if so, are they the same?
If you can connect to more than one network, are they all the same?
Are all network applications affected, or only some? If only some, which ones?
Is networking always the same, or is the problem intermittent?
Disconnect all other devices from the network. Any change?
If you're running a MacBook with the lid closed, open the lid. Any difference?
Start up in safe mode and test. Any difference?
Start up in Recovery mode. From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. Any difference?
If possible, turn off Bluetooth and disconnect any USB 3 devices. Any difference?

Removing battery from Lenovo Twist S230u laptop?

Hello. I am sending my S230u laptop by air to a Lenovo service station to get its HDD replaced. One of their requirements is to remove the battery from the laptop since it is considered a 'hazardous' material.
Is it actually possible to remove the battery off an S230u? I've been searching online and it appears you can only disable the battery. Any help would be really appreciated.
Thank you for your time.
Solved!

It appears I don't need to remove the battery after all.

Thinkpad Twist S230u: Clean Install - Windows 8 on Custom Partition

I want to install Windows 8 using my own partition configuration, meaning where I'd get a C and a D drive. On my other computers, this is what I have and I really like this configuration. I want to install Windows 8 on the C drive and have all my data on D. I have reformatted and partitioned the HDD to C and D. When I slot in Windows 8 Enterprise to install, I keep getting this message "We couldn't create a new partition or locate an existing one." What the machine keeps wanting is for me to delete both partitions and create its own partitions and I don't want this. I know it wants this because I have clicked delete of the partitions and looked to see what it would do. It ended up creating several of its own partitions (not at all how I want it). When I re-partitioned the drive back to C and D (2 partition config), it would repeat that same error message.
Can someone please help tell me how do I install Windows 8 doing my own custom partition (C, D) where Win 8 is installed onto my choice of C and D is left for my data. Why does it keep saying, "We couldn't create a new partition or locate an existing one"? Is it a settings in BIOS that I need to change to enable me to use my own partition? If so, what setting? I have never had these issues installing Win 8 using the C & D partition config on 3 other computers (not Lenovo S230u Twist).
Thanks for your help!!! :-)

Hello LightspeedX!
I glad you wrote this issue cause i still having the same problem (and questions).
I decided to put everithing down on my s230u because it is quietly irritant see a last generation porcessor like the I7 on a top plataform ultrabook running so slowly like our thinkpad do.
Since the embed software and the poor resource planning is the resposable for that issue, i really cant imagine why Lenovo decide to bring all this things up together at this device. I realize that any cheap I3 china device is more confortable and "quickly" to run any software than this machine in his original state (factory defaults), so i decid to try a brand new and clean installation of windows 8 or (perhaps) a dual boot configuration using a linux frindly distro like ubuntu.
At my own risc, like the cusummer service like to say, i will erase all HD and start this "saga" (making a full hard copy first, of course and will soon bring any results i found here.
