Distance-sensitive Wired Connection Issue

My 2009 Macbook Pro (Snow Leopard) seems to have a distance-related connection issue for wired Ethernet connections. I can connect the MBP directly to my router and have no problems. I have problems, however, when trying to connect to some outlets connected to longer cable (CAT5) runs. Other computers, both Macs and PCs, can connect fine to the same outlet. The Network Diagnostic for the MBP shows "No Cable Connected". With respect to the Linksys router, it either shows no lights for the connected outlet or sometimes shows all three lights blinking on and off simultaneously (a normal connection shows two lights continuously on and a blinking third activity light). I can connect the MBP to some ethernet outlets, most (but not all) of these have somewhat shorter cable runs (my best guess is that no run in the house exceeds 200 feet).
I have tried all the usual suggestions: toggling the router power, manually configuring ethernet, deleting and adding the ethernet connection, etc.
I have gone to the Apple Store and, no surprises, everything works fine. I am posting to see if anyone has any Ethernet settings suggestions or can direct me to a way of somehow measuring the signal level on the non-working outlets.

I have seen some weird things happen with newer Mac hardware and older Cat5 cables, even those that work with other hardware. Are you sure that those other wired connections are at maximum speed?
The best thing to do often seems to use a new Cat6 ethernet cable.

WRT55AG- Wired Connectivity Issues

I have a BEFW11S4 that has worked great for at least 2 years now. My setup is cable internet (from Comcast) to the router, with a wired connection to a desktop and a wireless connection to, at most, 2 laptops and an adapter I use to feed ehternet to my xbox 360.
A few months ago I purchased a WRT55AG, version 2. With the initial firmware, I was able to replace the BEFW11S4 fairly easily, and seemed to be ok for a day or two. Then I started having issues with internet connectivity (It was a while ago, but I believe the wireless network stayed up while internet was intermittent and/or disappeared completely to both wireless and wired devices. I can't recall if the desktop was have local area connection issues, or just internet dropped.). I put the BEFW11S4 back in and haven't had time to start testing again until recently.
Since I've tried to set up the WRT55AG again, I haven't been able to get an internet signal from my modem to the router. Further, when I have my setup modem-->WRT55AG-->wired desktop, I get an error saying that my local area connection is down. Modem-->BEFW11S4-->desktop gives me no such error. Wireless network connectivity works (although it seems intermittent), so I have been able to wirelessly apply firmware upgraded v1.79. I have tried every reset sequence possible between modem, router, and desktop. I am not a network wiz by any stretch of the imagination- I tried to feel my way through some of the MAC address cloning using the wireless connection to the router, but I'm not sure that would help if I can't get a wired connection.
If I can't get the router to acknowlege a hard line coming in with internet, or my desktop to acknowledge the wire coming in from the router, I'm not sure what I can do. Any advice?

Some more information- when I connect the WRT55AG to my Comcast (Motorola SB5100) modem, the 'Internet' light on the router does not respond. The same when I connect via hardline to my functioning Linksys wireless-b router.
However when I connect via hardline it to my access point downstairs (a wireless Motorola adapter with an ethernet output), the internet light comes on solid for a few seconds and then blinks.
By the way, with everything I try, when I plug the router in, Power is a solid green and Wireless A and Wireless G lights blink green. DMZ light is off, as are the port and internet indicators.
Any help would be appreciated. Wireless seems to work fine but I can't get an internet signal in through the hardline.

E1200 and Wired connection issue

My old linksys router died and I bought a E1200.
For now all I need to do is set up my wired computer, my son will not be here for a week with this laptop so no need for wireless setup yet.
I simply swapped routers, plugged in my desktop and my computer still shows a red X in the Vista network connection.
If I do not use a router and plug directly into the DSL modem I can connect to the internet, but when I insert the e1200....nothing.
Do I need Cisco connect to make this work?

Hi. That is a great idea actually to run the Cisco Connect software that came with the router because it will provide you the steps. You can start by plugging your modem to your pc and run it from there. It will be a step by step instructions.

Connection issue on new infinity

Hi, would appreciate if anyone can shed some light on the issue I'm having.
I live a fair distance from the local village, so I can't get full infinity, but I do have infinity to a certain point, then copper cable for the rest of the distance.
Well aware I'm not going to get amazing speeds, but I was estimated at getting between 11 and 18Mb (compared to my old 1.5Mb it's a huge upgrade).
Got switched on yesterday, and was slightly disappointed when I tried my first download. I registered max speeds of around 6Mb, so did a bit of snooping around looking at my settings etc, tried a router reset and looked at the connection speed. Something I also noticed was my upload speed is even worse than when I was just on normal BB, used to be circa 0.3Mb upload, now 0.16.
So I checked the connection status on the router, and it's showing a connection speed of 14.xxMb and upload was something daft like 0.18. So the upload speed marries up (even though it's rediculously slow) but the download speed doesn't make sense, considering I'm connected at 14Mb but I'm only getting download speeds of 6Mb (600kbps, whereas I surely should be seeing speeds of 1.4/5mbps)?
Am I right to think something is amiss here? To be fair I really don't mind the speed at the moment, I can finally stream youtube at 720, whereas 360 was pushing it before
There's a couple of thing's I'm going to try tonight, as I'm using a very old long run of cat4 to connect to the router at the moment. So I'll move the router close to the pc and try the cable that came with the hub. Also, haven't tried wireless speeds yet which would also show a problem with the wired connection.
I would phone up BT but really don't want to talk to India again as you just go round and round in circles.
Solved!
Go to Solution.

Cat4 cable consists of four unshielded twisted-pair (UTP) copper wires with a data rate of 16 Mbit/s and performance of up to 20 MHz.

Linux wired connection - need help?

Unfortunately BT were not help with my query?
I use ubuntu and until last Friday no problems, worked first time in connecting the internet (wired connection, old lap top I'm afraid).
Now it just says 'wired not connected' although it is.
Done all the usual checks - tested agains another internect connection, which was fine; new cable; amended the wired settings to manual and put in the varies settings.
Still won't work
I currently use BT hub but I do have an old BT voyager route so tested it on that. At first the same issues, then it found the 'wired connected' , had an IP address but couldn't connect to the internet. It only did this once, then wouldn't work again.
I have run out of ideas, help please!

Aaaah.. that explains a lot. I've always used Netgear right from upgrading the Green frog eleventy million years ago so I guess that's why I've never experienced that.
I see it even affected a windows user here... Us TuxXors to the rescue (International TuXx0R... F.A.B)

EA6900 Internet Connection Issue - Desktop connected via ethernet cable

Hi there,
I have an HP p6837c, 64-bit OS with Windows 7 Home Premium. It is directly connected to the EA6900 via ethernet cable. My internet connection constantly drops (as in variably every 5 seconds to 5 minutes) then re-establishes itself. I have no internet connection issues when directly connected to the modem. All of the wirelss devices that are connected via the EA6900 are working without any issue. My husband's laptop, which has Windows 8.1, functions with no problem when directly connected to the EA6900 via ethernet cable. We've tried swapping out the cable. We've tried adjusting the MTUs per Support's suggestion. Nothing has solved the issue
Any thoughts on what the issues might be? Settings? The version of Windows? Any help would be much appreciated!

Internet Service Provider and Modem Configurations
What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
What ISP Modem service link speeds UP and Down do you have?
Check cable between Modem and Router and PC, swap out to be sure. Link>http://en.wikipedia.org/wiki/CAT6 is recommended.
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask.
I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.
Router and Wired Configurations
Setup DHCP reserved IP addresses for all devices ON the router. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
Ensure devices are set to auto obtain an IP address.
If http://en.wikipedia.org/wiki/Ipv6 is an option on the router, select Local Connection Only.
PC 3rd Party Security Software Configurations
Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

Connection Issues with BT infinity + HH3

I have had BT infinity installed for a couple of months now and I have got some issues with the connection that I am getting.
Now the Internet connection speed is not a issue getting about 35mb wired and 26mb over Wi-Fi and is pretty stable.
But when using my iPad 2 and watching a youtube video even at the lowest quality (using the App or Website) sometimes the video will often stop loading at a point and will not load the rest of the video so the video will just stop. This does not happen on my laptop.
This also affects the BBC iPlayer App, where I cannot even get a programme to even start playing. This all worked fine with BT Option 3.
It also effects Apps like Twitter were loading new tweets in the timeline can sometimes take forever for just a bit of text.
My Xbox 360 also will not connect to the WiFi at "N" only at "G". Even though I have one of the new style Xbox 360's that has Wireless N. Also i find the Download speeds realy slow. Took nearly 30 Miniutes to download a 1.3 GB file compared to about 6-8 on my laptop.
The one computer that i connected to the HH3 via a Ethernet cable has the most issues where it can take many minutes to load up the simpliest webpage like eBay. This problem does not happen all of the time but useally a couple of time per week. And what seems to happen is you click on a link and nothing happens then everthing loads.
Has anybody got any of these issues as this laptop seems to be fine but the iPad will not also load the content, and the computer that shouyld be the fastest seems to sometimes be the speed of a dial-up Modem.
Apart from getting rid of the HH3 and getting someting like a Apple Airport Extreme are there any other soloution to why this happens. This is not what i thought BT Intinty would be like.

It could be a dodgy router but check the following first
1) All connections are set to use DHCP(automatic) rather than fixed IP addresses and that the IP list on the Hub does not contain duplicate entries.
2) As the wired connection is running slowly it is unlikely to be a wireless conflict but use Inssider 2 to ensure you are not using a crowded channel the HH3 is supposed to do this automatically but seems flaky
You could try getting a new Hub sent to you but unless you feel rich or have Apple shares there are cheaper cable routers than the Apple ones around & any router that offers PPOE will work. Plenty of reviews on the web and you can buy them from £20 up.

Wired connection doesn't work if cable is not plugged in at boot time

Hey all,
I started using arch a few days ago and I simply love it, but I have a problem. The wired connection doesn't work if the cable is not plugged in at boot time, or if it was plugged in at boot time, then plugged out and in again. Switching it off and on again via the gui has the same effect. I am using NetworkManager with dhcpcd, NetworkManager is started via systemd, dhcpcd is not, I let NetworkManager do that. When I started investigating this problem there were some remnants of netctl, but now NetworkManager is the only networking-related service started at boot time. When the cable is plugged back in, NM-applet shows that it's connected, and an IP address is assigned, but the connection doesn't work.
Here's some information regarding the system:
It's a lenovo G50-70 laptop, it uses the r8169 driver for ethernet. (I dualboot it with windows 8.1, but arch is default and all this stuff happens also if i only use arch)
The router is a Linksys EA2700/N600

Try to use dhclient perhaps? Might I also suggest letting systemd deal with the dhcp issue and not NM. That may seem incongruous but it is possible NM is mis-handling the dhcp hand-off to the network card. I'm no guru but I got thinking about this when I saw this in your output:

aug 26 19:15:40 arch_daboka NetworkManager[527]: <info> NetworkManager state is now CONNECTED_LOCAL
It is very possible that I'm mis-interpreting this information so please take it with a boulder of salt.

How do I disconnect from Wireless to use wired connection?

Hi - I'm new to this and I apologize if this question is ridiculously easy.
I am using a cable modem in which I have plugged my WRT160Nv2 wireless router. I am supporting three computers here in my home; my laptop (both wired and wireless), my daughters laptop (wireless only), and my desktop (wired only).
Everything works great and I have to give all the credit to CISCO and the excellent software which automatically solves every connection problem that comes up.
My laptop and desktop are connected to the wireless router via cable.
My question is strictly about my laptop. When I leave my office in the house and go into another room, I establish the wireless connection. Now I am back in my home office room, I want to use my wired connection. How do I do this? Do I need to disable my wireless connection so that my wired connection takes over? Again, I do have my laptop connected to the wireless router via cat5.
I want to do this strictly for the speed of the connection. I've read that a wired connection is double if not more in Mbps.
This laptop is running Win XP Pro, SP3.
I hope this furnishes enough info to assist in an answer.
Thanks in advance.
John
P.S.. I really do want to educate myself regarding the equipment I am using and not have to ask such basic questions. Are there any books or websites you can recommend that can start me out and go as technical as I choose to?

Windows by default uses the fastest connection possible. If you have a wireless and wired connection active at the same time it depends on how fast both connections are rated. Wireless connections tend to change depending on the distance. Wireless 802.11g goes up to 54 Mbit/s. Wireless 802.11n can go up to some 300 Mbit/s. Wired connections are usually either gigabit ethernet (1000 Mbit/s) or fastethernet (100 Mbit/s).
Thus, which is picked depends on your computer. You should check the connection status of both connections in the network connections control panel. It shows you the current wireless and wired speed (the latter won't change of course). Very often, the wired connection is preferred to the wireless connection. Now with 802.11n connections the wireless connection is preferred if your wired connection is only fastethernet.
As your WRT160Nv2 has only FastEthernet LAN ports you have to check how fast the wireless connection is. If you have a 802.11n wireless adapter in your laptop it may show up the wireless connection faster then 100 Mbit/s. Depending on the setting it may change occassionally between 54 Mbit/s and speeds higher then 100 Mbit/s which would lead Windows to swap connections. If you see that problem it is better to switch off the wireless in the laptop while you have a wired connection...
A wired connection is more reliable and stable then a wireless connection. With wireless you can have interference. Thus, even though a wired connection may be slower then a wireless one you may prefer to use the wired connection anyway. And some people prefer to turn off the wireless to avoid radiation.
To sum up: usually you don't have to switch off the wireless, unless you experience problems because of the mentioned changing speeds of the wireless connection. The computer will always only use one connection. Not both.

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.

BT Infinity Connection Issue/ frequent ping latenc...

Hi. I'm getting frequent latency over past few month. had Already spoken to agencies about the issue, but no reslovation appeared. So, hopefully, I can get some answer here. Btw, I already tried to switch between channels, reset to factory setting, turn off 5Ghz, it still doesn't work.
The ping latency happen randomly almost everyday in certain times of a day, last around 10 minutes. I got some proves showing the situation exactly at that time.

Can you run this checker and post back a screen shot of the results
http://www.dslchecker.bt.com/adsl/adslchecker.welcome
and use this speed tester then carry out the further diagnostics and post back a screen shot of all the results including your IP profile for up and down. This test must be done with a wired connection.

Apple Airprint to HP Officejet 6500A Plus via Wired Connection to Router

Hi There,
So I've done a considerable amount of research into this across the internet and this forum and I'm still struggling to find a satisfactory solution.
I have an HP Officejet 6500A Plus connected by ethernet into my BT Homehub 3.
It is my understanding that even though this is a wired connection, as long as my iOS device (iPad 2 or iPhone 5) is connected to the same router, I should still be able to see this Officejet over through the airprint facility.
Unfortunately this is not the case. I only get the "No Airprint Printers Found" message on both devices. The only way I have managed to get my Mac Pro (Mavericks) to connect was to mannualy add using the IP address for the printer.
Can anyone give any guidance as to what I might be doing wrong? The printer is definitely connecting to the internet as I can print from my iOS devices using HP ePrint app for iOS.
Some might say well what is the problem, just use the HP app but this is not point. I believe if something has been implemented to make things easier then use it. I chose this printer specifically for this functionality so it's a little frustrating to find it so difficult to achieve the desired results.
Hope it's something straightforward and someone can help.
Thanks,
Steve
This question was solved.
View Solution.

Further to this request, and reading many more similar issues, I think I may resolved this.
I am not 100% sure but I have read some threads suggesting there are issues around BT's Homehub 3 and bonjour so this may be an issue.
I have tried the following over the past couple of days...
1) Completely reset my router (wiped all settings and started again) - No luck!
2) Tried changing from WPA2 to just WPA security - No luck!
3) Tried forwarding the bonjour ports to the printer - No luck!
4) Switched off router, printer and all iOS devices then powered back router, printer and then iOS devices - Printer appears on iOS devices but when print was selected, iOS device repeatedly returned Printer Not Connected error.
Finally, what seems to have done it (at least for now) was...
1) Unplugged ethernet from the Officejet and set it up as Wireless connection.
2) Powered down router, printer and all iOS devices then powered back up in the order stated earlier.
3) So far I have tried printing an email and a web page from my iOS devices and both have been sucessful.
Incidentally I had been struggling also to airplay from my iPhone and iPad until I started messing around with settings above and now this issue also seems to be resolved.
Due to variety of combinations (different printers, routers etc) people will have, it seems to be quite difficult to find a solution which addresses an individual problem however I hope some of my experimenting and findings might help others in some way.

Wired Connection problem on Officejet Pro 8500 a909a

I am having what seems to be to be a strange problem.
I have lost connectivity to my printer (Officejet Pro 8500 a909a) through the network from my Windows 7 64bit computer. I found that it worked fine if I connect throught he USB port. Today, I have been trying to get back to being able to use it through the network.
I am able to get to the configuration on the printer through the network, at http://192.168.0.105 and that works fine.
I have downloaded the most recent software and when I run it, it doesn't detect the printer, even if I enter the ip address in the advanced search box.
I have downloaded the HP Print and Scan Doctor, and when it runs, I can see the printer, however i'm not sure why it shows 2 lines:
When I choose the last line and press next, all it does is goes to this page:
Your help is appreciated.

What operating system does the computer use?
What happens when you choose the network-wired option on that last screen? Since the printer is already installed, the software thinks you are wanting to install the printer again and presents the last screen.
Your printer is listed twice with two separate IP addresses. I suspect the issue may be that the IP address is changing to frequently for the detection protocol to keep up with it.
If the printer is on the network and you can access it by entering the printer's IP address in a web browser, you can try setting a static IP address for the wired connection. Click on the Printer Does Not Maintain Wireless Connection document from HP. The document is for wireless connections, but the same steps can be applied for a wired connection by substituting wired for any section that designates going to the wireless section of the printer.

HP Color LaserJet CP2025dn Printer Wired Connectivity and have USB simultaneously?

Hello to all;
Thank you in advance.
I have a HP Color LaserJet CP2025dn Printer.
The question, can I use ethernet connection and have USB simultaneously? Ethernet is faster, right?
Currently, I have the printer connected to network via Ethernet Wired Connectivity through an Apple Aiirport Extreme base station. I have several Mac's all operating under 10.9.1, and two PC's (one is WIN XP, and the other WIN 8.1), which all operate fine with 2008 wired/wireless technology. I know what a dinosour. I am in the process of upgrading the household to current wireless technology with a NetGear AC1900 Nighthawk Smart WiFi Router (Model: R7000), 802.11ac Dual Band Gigabit, with two USB ports ((1) 2.0 and (1) 3.0) . I connected the printer directly into the Netgrar router, and it wouldn't print, ran setup through the Mac and Win computers and still wouldnt pring. One of the reasons that sold me on the Netgear router was the ReadySHARE® USB access—Wirelessly access & share. In order for me to utilize the ReadySHARE® feature is to connect via a USB cable. Sob story, the longest USB cable off the shelf usually 16", and to reach where the printer is now, I need @25-28 feet of cable. Is ther a maximum length of USB that I can use with out suffering loss of speed/functionality?
Again thank you for your time

I am sorry, but to get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial printer. You can do this at http://h30499.www3.hp.com/hpeb/

Connectivity issues from Oracle to Sybase

Friends.
I have connectivity issue from Oracle 9.2.0.1 to Sybase 12.5 ASE .I am connecting through the database link in oracle to access the tables.
The error message i am getting :
select count(*) from TEST_TABLE@IND_TEST;
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
523 80
ORA-02063: preceding 2 lines from IND_TEST
Please guide me how to solve this error message. is it version incompatible now?
Thanks
Rocky

Hi,
You are now making the connection to the Sybase database but there is a problem with the user and password used in the database link.
Sybase is case sensitive for names so you need to surround the user/password in double quotes to make sure they are passed to Sybase in the correct case -
create database link ind_test connect to "sybuser" identified by "sybpass" using 'tnsnames_ora_entry' ;
where sybuser is the userid as created in Sybase with the password sybpass.
If they were setup in Sybase in mixed case then it would be -
create database link ind_test connect to "Sybuser" identified by "Sybpass" using 'tnsnames_ora_entry' ;
Regards,
Mike
