Network / Sharing :: Yahoo Mail And MTU Settings
Apr 26, 2014
There is this peculiar problem I'm facing with MTU settings.
I'm using PPPoE with wifi enabled on Windows 8.1.
Couple of months back:
ADSL MTU setting was promptly set to 1492 (8 bytes for PPPoE header discounted).
All of a sudden, yahoo mail was not accessible.
When I tried
Code: ping -f -l 1464 mail.yahoo.comPacket needs to be fragmented but DF set. Packet needs to be fragmented but DF set.Packet needs to be fragmented but DF set.
Packet size of 1464 (MTU:1492 - 28 bytes for adjusting different header size) is big. So decided to change MTU.
I checked for various packet sizes; First ping was OK for packet size of 1452. So MTU can be set at 1480.
I changed the MTU to 1480 in modem setting and restarted.
When connected, I tried yahoo mail again - and again failed.
I checked the MTU which is set at 1480. I tried ping with packet size of 1452 and got surprise. I got "Packet needs fragment" again. The same size was working earlier.
I repeated the process. Now the MTU came to 1460. I set the MTU again in modem and restart and try yahoo mail again to get the same failure.
Again I ping with packet size 1432. Nope. Got "Needs fragment" error.
Changed MTU setting in Modem to 1400 - retry cycle - same issue.
Changed MTU setting in model to 1300 - retry - same issue.
Then I came across setting MTU for interfaces in PC. So reverted the MTU to 1492 in modem.
Set the PC interface MTU as below. I set it for WiFi interface as I was using wireless Internet access.
Code: netsh interface ipv4 set subinterface "Wi-Fi" mtu=1460 store=persistent
This solved the problem.
Today I couldn't access yahoo mail. Checked the MTU setting for PC wifi interface. It has been reverted to 1500 (default). May be some windows update did that.
I set it back to 1460. Tried to access yahoo mail. Still not accessible.
Checked the ping with size of 1432 (for MTU 1460). Got "Needs fragment" error.
Checked ping with packet size 1400 - OK - change interface MTU to 1420 - Still couldn't access yahoo.
Checked ping with pkt size 1400 - now not OK.
Checked ping pkt size 1360 - OK - Change interface MTU to 1300 - still couldn't access yahoo mail.
Checked ping pkt size of 1360 - now not OK.
This seems to be vicious cycle. What is happening?

Appears browser related as problem is only in IE11. Have googled issue and can find no definitive answer. Clearing cookies, etc and resetting IE11 does not work.

Is there a way to setup network profiles or something so that when I bring my Surface Pro to work and connect to the wireless network there it will use the static ip address I have but when I disconnect and then connect to my home wifi it will go back to DHCP? On my MacBook Pro I can go into the network settings and change the location profile I have setup for networks but I don't see anything like this for Windows 8.

So, yahoo web mail's giving me grief on both this Windows 8 machine and my vista machine, which I'd done a fresh zero out and software reload on, neither machine will load yahoo messages, keeps spitting up error code 45s...
I saw they had a yahoo for windows 8 app available, lets try that! no such luck, yahoo mail Windows 8 app is doing the EXACT same thing.. sans the error code 45s.. Getting grief from their yahoo email?
The snapshot below is what it HAD been tossing up nonstop before the error 45s started saying hi.. as you can see..I had alot of mail tabs open on the mail screen..they were all spitting up errors.

I just sent my computer in to be worked on a month ago. I had this working before then
It was factory reset so this is a computer/browser issue, nothing with the restore
I had Yahoo Email set as default. For each of my previous computers, I did too.
I cannot find the link telling me how to do it: I remember seeing it could be done with a particular version of Yahoo toolbar And I saw one that would install the mail plugin with Yahoo Messenger
Neither has been there when I installed several versions.

Anyway to transfer back to the old Yahoo Classic ?
I have "googled" the issue but most possible solutions are outdated. One older solution was changing the screen resolution which supposedly transfers back to the Classic but this did not work.
I personally have not experienced any issues with the new Yahoo Mail as stated below, but just prefer the Classic format.

I am running Windows 8 and use Yahoo mail. Is there anyway to completely stop all those advertisements from reaching my email address without having to pay for software? I am using Avast, SpyHunter, CCleanner to protect my computer and routinely backing up my hard drive. I see Yahoo Mail offers something to block all their ads, but what a shock, I would have to pay them for a subscription.

It was working earlier but couple of hours later when I booted up my Windows 8 laptop.. There was a red x on the network I was trying to connect to and a message saying my computer settings not matching.
I looked it up on youtube and I tried selecting "No authentication" and for encryption type I chose "None". But still didn't work.
Sometimes it would say limited first then when I try to reconnect the message above will appear.

I can set up sharing of my internet connection with the WiFi hotspot connection and it works fine until I restart my PC.
Then it reverts to a different setting and I have to manually change it back.
Is there a way to make the internet connection sharing settings permanent?

I cannot connect to my wireless anymore (all other devices in my home do) since windows has automatically installed the drivers for my canon printer.
In PC setting i do not have the button wireless anymore (i am pretty sure that i had it last week). Wi-Fi (Qualcomm Atheros AR964x) is in my network connections, but cannot connect. Diagnoses says problem with wireess adapter or access point.
So what did i do until now : I have restarted the whole interne installation ( rounter, and all other devices) many times Atheros driver is up to date and device status is "working properly"
i dont know anymore what to do more (except switching to linux and not being able to use some commerical software i rely on for my work) :-(

Network Location - Set to Private or Public in Windows 8
I have a home network, several PCs connected to a modem/router (all with Ethernet cables), with ADSL access.
One PC has got Windows 8.1, with network settings as "private network", with sharing ("find devices and content") turned on. I am thinking about turning it off, to increase security, since I don't need to share files an printers.
My questions:
1) There is no risk to damage Windows by turning sharing on or off, with that "find devices and content" option in Windows 8.1?
2) After changing the sharing settings, I do not need to change any settings in Windows Firewall, such as resetting it to default?

I do a lot of AV system programming, which generally involves having to set my IP address for either my Ethernet port or WiFi card to manual IPs temporarily. I am having an issue on a relatively clean install of Windows 8 Pro that after I change my IP, when I go back into TCP/IP v4 to change it back to DHCP, it is already set to automatic... but if I right click on the connection icon and go to Status, it still has the static address. I tried to set it to another manual address and to hopefully go back in to revert, but that doesn't work.
The ONLY thing that seems to work is removing the NIC from Device Manager and then re-scanning for hardware changes where it will be automatically detected with DHCP enabled by default.
WiFi card is Intel Centrino Ultimate-N 6300 AGN.
Ethernet NIC is a Broadcom NetXtreme 57??.
I've got the latest available drivers, and using generic ones doesn't work. It's also on both NICs so I don't it is a driver issue.

I just got a network usb adapter for my new Windows 8 built PC. In the devices area of the control panel it shows the network adapter as installed, and working. However, when I got to PC Settings there are no wireless settings shown, and unlike my other computers around the house I can't find my network or any other networks which is very stranger since I live in an apartment and I'm surrounded by like 20 different networks.

Something keeps changing my proxy settings. Every time I change it to "Automatically detect settings", something is changing it to "Use a proxy server for your LAN..."

I don't want to use the DNS servers of my ISP and I don't know how many times I changed over to third party DNS
servers now.
But 2 weeks later when it occurs to me to check, they are almost always back to Auto, i.e. the ISPs.
Why does this happen and how can I prevent it?

I have installed Windows 8.1 on my laptop. My laptop is Hp 6510b. Windows 8.1 is working fine for me. But the only issue I am facing is that I am unable to see my Bluetooth in Settings. Hence I am unable to transfer files. My android is also not searching my laptop.

So I'm rolling along the internet and I start noticing that the wifi bars in the lower corner have gone down to 4. My internet is running slower and when I log on and play online games, the local server which gave me a 50 ping is now jumped up to about 300-800 easily...
So I run trouble shooter (and malware bytes) and this gem pops up:
"Windows cannot automatically detect this network's proxy settings."
I run google chrome as my internet browser, but as of late Norton has been blocking chrome and my wife started using Internet Explorer...but when we disable Norton, Chrome works fine.

I'm using Win 8 Pro and i'm on a Private network which happens to be my Home Network. I'm having problem saving HomeGroup settings; I went through Change Advanced Sharing Settings then I checked Turn on network discovery and Turn on file and printer sharing, I clicked save and but when I return to the setting page again, the settings are not saved.
I've tried this several times but nothing seems to be working out. The same thing still happens when I go through Charms >> Change PC Settings >> HomeGroup >>Libraries and Devices.

The Windows App Store will not open. It spends a while thinking about it, then eventually times out. I would like to update to 8.1, but I think this is evidence of a bigger issue.
I think the real problem in my proxy settings in IE. The LAN settings have the Use Proxy Server permanently checked. No matter what I try, it wont uncheck. I have tried selecting the automatically detect settings box and putting in a dummy config. I ran Malware sweeps, ran virus sweeps, I removed any IE Add-ons. Reset IE. But it still wont let me uncheck that box..
It looks like there is a manual override within the Registry.

I signed up for a DNS service a while back. When I stopped using their service I removed their DNS entry from the ipv4 settings and considered it done (this was all they stated for install/uninstall, just update the DNS in ipv4)
At random, the PC will revert back to their DNS server. I have no virus (Malewarebytes Pro), my hosts file is empty.
Here's what I've done:
1) Removed it from ipv4 settings manually and reset to Obtain DNS Automatically
2) Open cmd as admin and ran the following sequence:
ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
netsh winsock reset
netsh int ip reset
3) Reboot
On reboot, everything is normal, anywhere from 24 hours to 30 DAYS later it automatically reverts back to their DNS servers. I am on a .edu domain. I do not have access to the router, but I never modified anything in the router. Why my PC keeps reverting to their DNS servers?

I'm a new user to Windows 8 and am having some problems. First, everytime I try to open the store it tells me I'm not connected to the internet, but I am. I've tried running the troubleshooter, but it does nothing. Additionally, I tried logging into Mail, but all I see is a three-tone white screen that has zero information on it. And yes I had an Outlook account before Windows 8. Last, I receive warnings about certificates with many websites I visit, including a few run by Microsoft. If I'm not mistaken, all of this is caused by McAfee controlling my firewall, and I seem unable to disable it and regain control of my new computer.

I was just wondering whether Windows would control how Thunderbird sent desktop notifications?
If I email a message to the account set up with thunderbird it appears instantly(ish) in the program but if I'm in another program and send a message I don't get any pop up notification from thunderbird....

I seem to recall that when you change the proxy settings for Internet Explorer, it's not just IE you are changing. IEs proxy settings are somehow the proxy settings for other apps and the OS as well. What connections are affected if I add a proxy in IE?

I accidently added the "Yahoo Toolbar" to my MIE-11.
I followed the standard instructions for removal.
I went to "Tools" then "Manage Add Ons".
The list of Add Ons appeared. When I click any other Add On in the list the "disable" button lights up.
When I click on "Yahoo Toolbar" the "disable" button does not light up so I am unable to get rid of the toolbar.
While on MIE11, I tried clicking on the "X" at the left side of the Yahoo Toolbar. Two choices appear :
(1) Hide Yahoo Toolbar temporarily
(2) Disable Yahoo Toolbar permanently.
I can Hide the toolbar but when I click on the option to permanently disable the toolbar I get a message that says "This action is restricted. Contact your system administrator".
Went to control panel uninstall software , couldn't find Yahoo Toolbar on the list !!!!

Windows XP did all I ever needed. Heck! Windows 2000 did all I ever needed. I use the phone only as a phone. But I do need email.
Got a Nokia Lumia 520 last month. Set up an email account xxxxxxxx@live.com
Thrashing around with Windows 8.1, now that XP has gone off support. Set up a Windows account xxxxxxxxx@outlook.com.
Still not understanding the difference between 'live.com' and 'outlook.com', but I am able to access email on both these accounts by login with a browser.
But I do not work my email through a browser. I use Thunderbird, and preview with MailWasher Pro to purge any junk from the server.
After over an hour thumping around, have not been able to get Thunderbird or MailWasher to work either the 'live' or 'outlook' account. Maybe problem with pop and smtp addresses. Beginning to think Microsoft allows only working the mail through a browser.
The email account which I actually use, and depend heavily upon, is tied to my ISP. Am considering change of ISP, and therefore a change to a non-isp linked email - like gmail or outlook. BUT... if I can't get Windows emails working except through the browser or phone, Windows email is of no practical use to me.
Any link to something that explains the difference between Windows 'live' and 'outlook'.
