SF-302 switch connectivity issue

Hi Forumers'
i found that cisco small business SF302 PoE managed switch connect with the end device (RFID component) would causing packet drop issue.
how should i isolate the issue and proper troubleshooting? would it cause by the PoE issue, or the 10/100 base etc.
any suggestion are welcome, thank you
Noel

Hi Noel,
Interesting series of exchanges, sorry for jumping in Mr Carr.
Alarm bells ring in my mind, when you say ". Switchport is running o autonego, so the switch prefix it to 10-Full, any ohter mode than this is not working."
Did you manually set a port speed to 10-full or does autonegotiation settle for 10-full?
Can you also check within the RFID device, what it thinks is it's link speed and duplex ?
( if the switch port or the RFID device have their speeds manually set, then the NIC/switchport autonegotiation process WILL not work. for autonegotiation to work, both the RFID NIC and the switch port must be set to autonegotiate)
I am thinking there is a autonegotiation or flow control issue between the RFID device and the switch. A previous cisco Question and answer section says (in blue) that ;
Autonegotiation issues can result from nonconforming implementation, hardware incapabilities, or software defects.
Noel, this brings up a point, have you checked if the manufacturer of the RFID devicefor the latest NIC driver firmware ?
Please be diligent and check this with the manufacturer of the RFID device, as these issues can be caused by old firmware..
When NICs or vendor switches do not conform exactly to the IEEE specification 802.3u, problems can result.
I think you have flow control to work with , but now I can understand packet loss, if the is a autonegotiation issue then packet loss can result.
Hardware incompatibility and other issues can also exist as a result of vendor-specific advanced features, such as autopolarity or cable integrity, which are not described in IEEE 802.3u for 10/100 Mbps autonegotiation.
It could be very interesting to see a screen capture like the one below;
1. of the Etherlike statistics for the port that is connected to the RFID device .
2. the error log, might be very informative to indicate a potential cause of this issue.
But, in the back of my mind, seeing 10megFull duplex as a setting tells me that autonegotiation is having issues, which points me to a NIC firmware issue in the RFID device.
You must be good and try to get a updated NIC drivers for the RFID device.
regards Dave

X1 Carbon (20AX series) wifi connectivity issues

Dear Lenovo Support and all others,
I am posting this in hope that someone can help with my problem and also to share my unpleasant experience with a new Lenovo product.
Lenovo Thinkpad X1 Carbon
Model: 20A8A00VSG
OS: Windows 7 Pro 64bit
Purchase date: 27th February 2014
Since the first day I purchased the system, I have been having an issue with my wireless connection:
1. I am unable to reliably get a wireless connection to wireless access points (e.g. free wifi coffee outlets or malls) and personal mobile hotspots (mobile phone hotspots). It constantly says "LIMITED CONNECTIVITY". In other words, I cannot get internet access. Even when it does connect to the network and get internet access, there is a tendency for the connection to drop back to "LIMITED CONNECTIVITY".
The only time I can get a reliable connection is when I am connected to my home wireless router. The system does not seem to have problems on home wifi networks. Since the problem seems limited to wireless access points and hotspots, I believe its a hardware/software problem.
Please note that I have other wireless devices (laptops and mobile phones) that can connect to the same networks that I am trying to connect to and have no issues.
I have tested the networks with my friends' wireless devices as well and they have no issues accessing the internet so I am fairly certain that there is no issue with the networks themselves.
2. I have already called in twice and been given advice on both occasions but the problem still persist. I have updated all drivers, uninstalled and reinstalled and updated the BIOS for the system and also performed a system recovery but nothing has worked so far.
I have also tried disabling and/or deleting any anti-virus software and firewalls but it does not fix the problem.
I have also been advised that I need to go down to the Lenovo service center to have my laptop checked out by the technicians and that there MIGHT be a firmware upgrade for the wireless card itself.
NOTE: MIGHT? The support staff doesn't even know for sure whether there is an upgrade available.
3. Rebooting my computer, the wireless card or the hotspots does not solve the problem. It might work for a shortwhile before it reverts back to it's non working state or stops working again once I reboot the system.
I am really unhappy with the purchase so far. It's actually a good laptop per se when all is working, but without internet access, it is pretty much like a dead fish. And thats 90% of the time.
Like I said, this problem has been happening since day one and I've tolerated it long enough.
I hope someone can help me with this problem.
Thanks all.
UPDATE - 3/24/2014
I borrowed an ASUS Wireless USB adapter from a friend and installed it on the laptop. Lo and behold there are no connectivity issues to my iPhone wireless hotspot.
INTEL DUAL BAND WIRELESS AC 7260 - NO CONNECTION/LIMITED ACCESS
ASUS USB N10 WIRELESS ADAPTOR - CONNECTIVITY AND INTERNET ACCESS
I think this narrows it down to the software/hardware in the computer....

Hi, all
there is an issue bugged driver or even card firmware related. Intel confirmed that. Wait some time for the new release.
For the test purpose only disable 2,4 ghz band support and switch to 5 ghz. N-band seems unstable so switch to G-band. As the Linux users report the same issue it's firmware bug basically.

Multiple Internet Connection Issues

Hi there, long time reader first time poster.
I figured I should post this as, while having read through hundreds of similar posts I still can't figure out how to solve my connectivity issues.
I just bought a new iMac 21.5 inch 3.2Ghz i3 model and while I am happy with the machine overall, it is the second one in a month - the first had a faulty ethernet port and refused to connect to the internet out of the box. Apple replaced it without question - almost as if they knew.
The replacement has now seemingly developed the same issue.
Some background info. The computer was connected both through ethernet and through the TC I bought to back it up until yesterday. So I was getting both a wireless signal from the TC and one through ethernet.
I have a hub that has 5 devices connected to it ( Printer, Cable TV, iMac and TC - now a PS3 ) That hub is served a signal by a simple NTT modem connected to a phone line. That modem is now nearly 5 years old but has always given great net speeds so I don't believe the problem to be the modem - I could be wrong though.
I just bought a PS3 and tried connecting it yesterday but had multiple problems. Despite me entering the correct PPPoE information to the letter, the PS3 refused to connect, saying the password and username was incorrect. I could connect it via a Bluetooth signal but no hard wired connection would work.
So I unplugged everything from the hub, shut down all the machines, turned off the modem and let it sit for 10 minutes and then plugged the ethernet cable from the PS3 straight into the modem, giving it a direct line. Switched on modem, rebooted PS3 and tried again - this time it connected through ethernet. I still don't know how or why. I can guess but I'm sure you guys know much more about this than I do.
So then I tried connecting the iMac back to the net, reconnected all the hub, followed the same procedure. Off, sit for a bit, on etc. This time the PS3 has no connection and now the iMac has no connection either!
The TC gave a green light though so I was able to get wireless. I tried removing all net locations from the iMac, installing new ones, renewed the DHCP lease, but no matter what I did (PPPoE info 100% correct) it just refused to establish a connection.
The the bloody TC light flashed amber and I couldn't get wireless either despite being plugged into the hub and getting a signal! The PS3 is now working and the cable is fine so I am starting to think either I have cluster ****** the whole setup or something is wrong with the iMac.
I go away for an hour then come back and the stupid TC has somehow picked up a connection! The light is green again?! But now the time connected display is scrolling repeatedly. I've got net but what the **** is wrong with all this?
Bottom line - not ethernet connection for the iMac but TC seems to be working and all other devices have a connection.
Please help me if you can! I just can't figure any of this out.

Your description is a bit confusing, but I use English as a second language, so it may be just me.
1. How is the hub connecting to your modem, by ethernet cable or wirelessly?
2. Which device is negotiating the internet connection with your ISP, the modem?
3. Does the device that negotiates the connection use PPPoE?
4. How are the other devices being handed their internet connection? DHCP only?
Only one device should be connecting directly to your ISP using the PPPoE protocol and configured with your account username and password. This device is preferably the modem. This device should be configured to hand out internal IP addresses to the other devices on your LAN using DHCP. All of the other devices should be configured to request an IP from that device, whether by ethernet or wi-fi, just with DHCP.

My MacBook Air has recently started having substantial WiFi connectivity issues. How do I fix this?

For the last couple weeks my MacBook Air has started having some mighty substantial connectivity issues.
When I wake it from sleep, or if I'm using it for an extended period (say, more than 5-10 minutes), the connection will become extremely unreliable. This primarily happens with browsers, or the Twitter application. For example, if I start a call on Skype the call will continue to function just fine, but I won't be able to connect to any websites through any browser. I've tried Safari, Chrome, and Firefox while the connectivity problems are occuring. When they do occur, a full shut down and cold boot are required to make it work again for a short while.
Does anyone know what might be causing this? I've done numerous checks for malware using Clam Xav and Sophos Anti-Virus. (I didn't suspect that this would be the issue, but it was still something that I decided to rule out.) Additionally, I've tried connecting using both the 2.4GHz and 5GHz bands on my wireless router. Neither seems to be more successful than the other. (Note: The 5GHz works perfectly and without interruption on my iPad and desktop PC. The 2.4GHz works perfectly with my iPhone 4S and Xbox 360. I feel that with that in mind, I can safely rule out the router as the root of the problem. Both of these examples go on for very extended periods of time. I game regularly using both my PC and Xbox 360.)

Hi Jollified,
Does your sound work when you try to use head/earphones? If so, try the following:
Plug your Headphones into your Mac.
Play a sound through them (a song for example), then stop the sound.
Make sure 'Preferences' is isn't open. If it is, Quit.
Launch System Preferences > Sounds.
While the Sounds tab is open and set to 'Headphones', pull out the Headphones from the jack.
You should see your Mac reset to 'Internal Speakers'
Also, I see you have tried resetting the PRAM, have you tried resetting the System Management Controller (SMC)? Resetting the System Management Controller (SMC) on your Mac - Apple Support
As for your MacBook not sleeping when you close the lid, there are many reasons this can occur.
First of all, check out Apples article on the issue: OS X Yosemite: If your Mac won’t go to or stay in sleep If you find these steps don't help, try a few of the following:
A common cause for the Mac not sleeping is your printer. If there are queued jobs waiting to be printed, but your printer is switched off, for some reason you Mac just wont like it and simply will not go to sleep. System Preferences > Print and Scan > Open Print Queue
Do you have an Ethernet Cable connected? People have reported in the past that removing their Ethernet allowed their Mac to sleep. This goes for other things you may have connected directly to your Mac also.
Try heading into your Mac Preferences > Sharing and deselecting 'Internet Sharing' as well as 'Printer Sharing'.
Also deselect Wake For Network Access by heading to System Preferences > Energy Saver > Power Adapter > Wake For Network Access.
Energy Saver > Schedule > Startup or Wake - Uncheck.
Alternatively, set your system preferences to Never Sleep, and put into Sleep manually: System Preferences > Energy Saver > Computer Sleep > Never.
Good luck!

Poor connection issue sends message "Verizon customer is not available" to callers rather than to VM!

My phone is my business. It's the only way I have for clients to reach me to schedule appointments. Most of my clients are new at this point. While my latest of 5 replacement phones don't drive me AS crazy with connection issues, it's driving my husband crazy as he daily gets told I'm not available and can't even leave a voicemail (which is usually yelling at me to dump this piece of crap phone). If he gets that message daily, I wonder how many clients I'm losing from getting the message as well!! With corporate discounts of 25%, I have still spent over $450 on this phone, all but the screen saver at the Verizon store. I was given the option of "upgrading" to a Razr last time. PLEASE! The CR tried telling me it was newer (don't think so, pretty sure it was on the display right next to my Nexus in Dec), better camera (very debatable, and with much lesser quality screen, who cares about more mp?!), and that I bought my phone 8-9 months ago but it had been available much longer. Umm, I bought it the week it was released. I don't think 2 days can be considered "much longer".
I'm going to try the switch to straight CDMA that seems to work for some with connection dropping, because I can't afford clients getting that message (they understand being sent to voicemail if I'm in a session), but... I bought this phone with a price tag of $299, paid another 99 for insurance, screen saver, gel case, extra battery and charger when my first phone port was shot after 7 months waiting for replacement, and luckily haven't bothered w/ screen savers for the weekly replacements or I'd have to add another $100 to the cost. This is a flagship phone with a flagship starting contract cost, and the best they can do is send out refurbs that have the same issue over and over. My guess is the turnover is so great they don't go through the normal testing and repairs of typical refurbs. Take these refurbs off the market when they're returned with bad radio! I'd consider a GS3, Razr Maxx, or maybe even the upcoming RazrM (though that would def be a downgrade considering the starting cost and we don't know yet of what issues it will have, but I like the size and battery life), though it sucks that I'd be spending another $50 just on case and screen saver.
Anyone else experience the unavailable issue and get it resolved? I'm so tired of calling tech support. And why can't they just put the phone number right on the "contact us" page like normal companies??

I certainly understand the need to have an operable device! Please DM me your name and mobile number, so I may further assist you. Thank you!

Connectivity issues for random phones in CUCM 8.6 on Vmware

I have a client that has problems with around half of there ip phones (6921 & 7945) after a situation with overheating in the serverroom.
The solutions was a 1 Publisher, 1 subscriber setup with each on a separate Vmware server.
The Publisher is connected to the Core Switch which is further connected to 4 distribution switches which again connect to 5 more distribution switches. They have around 200 ip phones connected to these switches that get assigned IP's with DHCP.
The physical disk that the Subscriber was on was destroyed the incident. The Publisher they recovered, but to do this they had to recreate the vm descriptor file and attach it to the flat-file.
So the current situation is that the system is running with only 1 Publisher and no Subscriber.
There is also a license warning in the CCM Admin section, stating a License Overage (2 nodes used, but only 1 licensed.)
The license status is not invalid though, and the license state is "Uploaded". This second node I suppose might be the Subscirber that no longer exists? The phones have more than enough licenses.
When powered up the system seems to run as it should, but only about half the phones have connectivity to and can register with CUCM.
I have tried to reboot some phones remotely by cutting the power on the switch interfaces where they are attached, but that made no difference.
The console log on the phones that are down show TFTP Timeout & File Transfer Error.
The phones that are up and running can be pinged successfully from the CUCM cli, but when pinging the others I get "Destination Host Unreachable".
The strange thing is that it seems completely random as to what phones are up or down. On all switches there are connected phones with both working and non-working connections to CUCM.
To try to pinpoint the fault I chose 2 devices on the same switch and compared the config for each interface, one that has connectivity and is registered, and one that does not have connectivity and is unreachable.
Everything seems to be identical so I can't see what causes this error on the one, but not on the other.
Also when I ping the ip phone with no connectivity to CUCM from any of the switches, the ping is successful.
Anyone know what could be the cause of this behaviour?

Hello and thank you for your time.
The phones get there IP’s from a DHCP Server (Not the built in one in CUCM, but an external server). I have tested that the DHCP process works by powering off a phone (one of the phones with connectivity issues), deleting the lease, and then powering the phone back on and seeing the device request and receive a new lease.
There is only one CCM group active and both servers are in this group with the Publisher as highest priority server. All phones are in the same Device Pool attached to this group.
There are a lot of warnings regarding dbReplication & missing node due to the subscriber being gone. Also there is an issue with NTP server (see below). I will post more on this tomorrow morning.
I have also attached the console log from one of the phones that can't register.
NTP Alert:

HP Slate 21 Pro: WiFi connection issues

Hi,
I recently ordered two HP Slate 21 Pro devices. Unfortunately, both of them have WiFi connection issues. After some time the properly configured WiFi connection will be dropped, which results in connectionless devices. The WiFi AP is disabled after this, and so a timed reconnect will not succeed.
After inspecting the Logcat I found following lines:

Is this issue already known? Has someone a solution for me?
Thanks in advance,
Christian

That really shouldn't affect it.
I'm a little stumped because I haven't seen this issue with this device before. The only similar issue I found was this, and it's unresolved.
Have you tried doing a hard reboot of the Slate 21?
I work on behalf of HP (But this isn't my job)

Wi-Fi connection issues since securing network

Hi all,
Hoping to get some solutions as I have tried to troubleshoot this issue with other posts and google searches. Here is my scenario :
I'm running OS Lion 10.7.5 on my MBP and have been connected to our home wi-fi for about 12 months on a connection that wasn't secured by password.
Since having some download issues and fearing that someone is connecting outside our household, we have secured our wi-fi and added a password.
Both mine and my sister's iPhones got prompted to select a network, selected the appropriate one, punched in the password and were connected with no issues. My iPad Mini, Dad's laptop and both my parents' phones all connected with no issue.
When I booted my MBP, I was prompted with needing to join a new network and upon selecting our home network was met with an immediate 'Connection timeout' response.
I try to connect manually through Network in the System Preferences and got the same 'Connection Timeout'. When I click 'Assist me' and try to connect that way, I am finally prompted to input the password, which I do correctly and I get 'Invalid Password' etc etc response ... then after about 5 seconds it connects me !!
So even though the connection timed out and I wasn't able to put a password in, manually doing it told me the password was wrong etc then I get connection like normal. If I switch my laptop off/reboot/log out/turn wi-fi off then back on, I'm back to square one and can't connect unless I follow the same tedious steps.
Fearing it was an issue with our router, we have since bought a new one, installed it and reconnected all the devices as mentioned above, however my MBP connection issue still exists.
How can I get it to connect automatically like it used to and recognize our home network with a correct password, without continually having to go through all those steps ?
I have tried to delete that entry in my preferred networks and tried to re-establish it etc. Keychain Access doesn't list my router and input password.
I'd like to be able to solve the issue asap if possible and hopefully without having to delete all of my other known networks that I connect to as I travel all over the country for work and have about 6-8 routers I connect to, depending on what city/office I'm in.
Any assistance would be appreciated !

Some users with various Wi-Fi connection problems have reported that they were given the following instructions by Apple Support, sometimes with success. I can't vouch for this procedure myself. After completing the procedure, you'll have to recreate all your settings in the Network preference pane. Make sure you know how to do that before you begin. Taking screenshots of the preference pane may be helpful.
Step 1
Back up all data.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 2
Reset the System Management Controller

Switch to Switch Connection

Hi, for one project we are using HP 1910-24G-PoE (170W) Switch (JE008A) switch. There are total six nos. of switches at different floors, out of these six switches one switch is located in main server room.
My first question is can we use SFP port available on each of five switches & connect it to one fiber patch panel through different LIU's ?
Sencond question is can we covert these into cat6 (RJ45) again & connect it to 6th switch located in main server room?
Thanks.

Hi Shashikant,
I given few thought what could be issue and following are few of the guess
Switch to Switch should be connected with cross cable -- It is connected
Both the ports should have same speed and duplex setting -- It is shared and OK
Possible Layer-2 loop - Needs to verify for both switches- Need topology view (if these switches are connected to any other networking devices)
Output of show cdp nei
Output of show spanning-tree
Output of show vtp status
Shutdown interface and then no shut the interface. Check the logging message on both the switches.
With this certainly you would be in position to identify the close the problem.
With regards,
Shailesh

HT6065 wi-fi connection issues - STILL?

For almost a year - I have been trying to troubleshoot wi-fi connection issues on my Mac Pro. It all seems to coincide with installing OS X Mavericks. I thought through recent updates OS X Mavericks v10.9.1, 10.9.4. the problem would be resolved by now. I eventually gave in and "hard wired" my printers and my iPhone only works via USB. I even have to resort to using an Ethernet cable plugged directly into my modem use internet.
I recently purchased an Apple TV with every intention of sharing my iTunes Library and playing my music on the sound system attached to my TV. Unfortunately, more time wasted trying to troubleshoot what may likely be another Mavericks wi-fi connection issue; see discussion Home sharing is turned on - not working
Here I am now in the Mavericks discussion group trying to find a solution - I have read about the same issues with other Mac users and some have switched back to Mountain Lion and re-enabled wi-fi usage on all wireless devices; while others suggest third-party apps as work-around solutions. I am reluctant to go to what I would consider "extreme" measures to fix what seems to be a well documented issue.
Any tips on reverting back to previous OSX - Mountain Lion, or shall I wait until fall for new release of OSX - Yosemite?
Thank you in advance - Db

BRI-to-PRI Connectivity issues

I'm having some serious BRI-to-PRI connectivity issues, and I was hoping someone out there could offer some assistance. The devices call one another perfectly, but they just both send magic numbers out and never get the data from the other device so they are unable to setup a layer to connection.

Steve,
I have seen this issue many times before and it always turned out to be an issue on the Telco network. It's quite possible either the line itself or some equipment on the provider network mayn't be provisioned for DATA or faulty equipment on their network.
Let us know how you do with it.

Bluetooth connectivity issues after updating to OS X 10.10.3

I have been experiencing issues with bluetooth mouse connectivity (apple magic mouse) after updating OS X to 10.10.3. My Macbook Retina 15" pro (early 2013) keeps losing connection with the mouse. Switching the mouse on/off helps in re- establishing connection between the mouse and the laptop for a few seconds. I was under the impression that this update of Yosemite was intended to rectify bluetooth and wifi connectivity issues. Any suggestions/advice welcome.

Back up all data.
Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/com.apple.Bluetooth.plist
Right-click or control-click the line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combinationcommand-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

Seeking to fix this error: "Failed while adding virtual Ethernet switch connections."

I am getting the error below when trying ot make modifications to my Hyper-V.
I am trying to add a new Virtual Adaptor.
Hoping someone may have a suggestion on how to fix this.

Alex just a quick response to your advice re disabling AV, this did not work for me, after more searching the internet for a solution I found a post from 2013 where one poster offered the advice to go one step further, and it was to remove the AV package
completely, the package in question was KIS2013. I have KIS2015 and figured I would try it as I was getting a little frustrated with the constant failure to create a virtual switch.
Anyway, it worked for me, I removed KIS, rebooted, and the VS was created on the first attempt without any issue. So simply pausing/disabling the AV from within the AV program may not be enough, I suspect that some may work and others not, as in the case
of KIS. I wonder also if you disable the AV services at start-up if this would also work but I did not try it.
Anyway to other people experiencing this issue, I suggest disabling AV first as per Alex's advice, and if this does not work for you then suggest trying to remove the AV before doing anything more drastic like re-installation of OS as I have seen suggested
in more than one place.
Thanks
Mr Bee
--EDIT--
Just wanted to add, it is also worth 'excluding' any Hyper-V folders from the AV engine, I did not try this before removing KIS2015 so it may work without the need to remove your AV product, but on re-install I have now exluded the folders as suggest by
a few folks in various posts...

Intermittent connection issue

I am having connection issues again as I did 2 years ago. The connection gets dropped intermittently. Sometimes the modem has a red light on the internet indicator and other times the DSL blinks and won't sync. The tech gave me a new modem, but I still have the same problem. 2 years ago the problem got resolved when they switched me to another line. I keep a spreadsheet on the tranceiver stats. The margin dB varies 20.2/21 (down/up) to 8.8/21 to 18.1/29 for instance. Line attenuation stays pretty much the same between 51.4/29 (down/up) to 49.4/29. Tranmit power varies 9.3/11.9 to 15.7/11.9 to 16.2/11.9 (down/up). I cannot seem to get someone to fix the line issues coming to my home. How can I get this fixed?

No, it is still ongoing. I have a field tech working on it. I was away for some days so couldn't respond. As you know about the intermittant connect problem because of an unconditioned line. Also, I was unable to obtain 1.5Mb/sec connect speed and Verizon only gave me 1.1Mb/sec. This week I am unable to connect at that speed and is now only 0.928Mb. I don't know why this happened, but I can tell you I am unsatified with this connection. I am really unhappy with not being able to get a measly 1.5Mb/sec connection speed when the rest of the world is getting 50Mb/sec or greater speeds.
As a stock holder of Verizon I am even more disappointed in their neglect with the DSL service. I am working on a letter to investor relations on this matter.

Connectivity issues after 8.1.1 update please help! :(

Hi all. Here's the situation.
I got my Iphone 6 on release day.
Not had one single problem with it.
On Monday however I do a general software update to IOS 8.1.1
Now ever since then I cannot keep a steady connection to both WIFI AND my roaming internet.
BOTH show as connected however load EXTREMELY slowly or not at all. No matter where I am.
I have done a soft reset.
Switching on and off.
And resetting Network Settings.
Done all these 3 or 4 times and they are not helping.
It is too coincidental to not be because of the software update.
Can someone please help me?

Still no help for you? I updated my iPhone 6 to 8.1.1 this past weekend and now have huge connectivity issues too. My home WiFi signal is 5 bars but runs very slow for example Facebook, the phone cannot update messages or photos. Try to connect for online banking, forget it. I have turned off WIFI and try using my Verizon signal which is 3 out if 5 bars, same problem. Don't understand why Apple cannot fix this apparent bug. Will call Apple Care in a few minutes and let you know what they say.
