Because I live in a small space I've been struggling with wifi interfering with my bluetooth devices.

Things I CANNOT do:
  • Move the router farther away: It's already as far away as it can get (about 5 feet).
  • Use the 5GHz frequency: The wifi devices in question only work on 2.4GHz

Things I've already tried:
  • The transmission power is set to low
  • Disabled Smart Connect

What settings can I change on my D-Link AC3200 router in order to make it interfere less with bluetooth frequencies? Some options are to change the wi-fi channel from 11. Other options are to change the 802.11 mode or channel width.

I spent good money on this router years ago before I used bluetooth much. Now I use bluetooth much more. Should I sell this router and get one which behaves better with bluetooth in small spaces? Other than the bluetooth interference it's been a rock solid router even when I lived in a much larger space.

My primary bluetooth uses are headphones and video game console controllers in case it matters.
I had a printer exported over WiFi on my Windows 7 desktop system so I could print on it from other computers in the house though their WiFi connecton.   Then I changed the Windows 7 internet from Comcast to AT&T.  AT&T gave me a new router with a new WiFi network name and password, so the other computers could no longer find  the printer. I redefined the WiFi connection on the other computers to the AT&T WiFi but  I'm still not prining from the other computers.  it seems the printer on Windows 7 has been exported to the Comcast router, which is dead now.   So how do I export the printer on my Windows 7 system to the new AT&T router.  If I can do that I expect the other computers will see the printer now that their WiFi points to the AT&T WiFi.

Thanks for any help.
I own an Avaya ACS509 R7 BUSINESS PHONE SYSTEM NAMED PARTNER. One of the extensions,the main programming extension number 10 is not functioning 100%.There is an illuminated button that can be designated as DND (Do Not Disturb). The button does make a click in the receiver but does not turn on the DND feature nor does the led come on. I have tried several identical phones on that  line and none of them work. All of them work different extensions. So, I must assume it is the main controller board. I am an Electronic Technician and probably can repair it IF I could locate a complete schematic diagram along with pcb board layout pictorials and part numbers/values. I do NOT need the programming manual or user's manual. ONLY a technical repair manual. They must exist somewhere since there are several locations that will repair this motherboard. I would really appreciate it if any Expert could direct me to a pdf or similar for this unit. It is also referred to as an ACS-R7 unit. Anyone assisting me will be the recipient of 735 virtual Kudos!

NOTE: This is NOT a voip system. Just a regular 20 extension phone system.
I am attempting to connect a Dell PowerConnect 2724 on port 24 to Cisco 3560G on port Gi0/3. I want to be able to pass through traffic from VLANs 30 and 34 which already exist on the Cisco switch. How do I need to configure the ports I mentioned above? Basically we are using this switch in our location to connect laptops to do imaging and other work. Thank you for any help you can provide!

The goal is to run dual internet connections simultaneously using an  AT&T PPoE DSL (yes, PPoE DSL) connection and a Verizon 3G/4G Wireless USB Modem and designate specific office computers to use a specific internet connection.
A few of the computers run remote backup jobs that we want to connect to the un-metered AT&T connection.
A few of the computers need to utilize the faster Verizon 3G/4G connection.

Planned Equipment purchases:
One Sonicwall TZ 300
One Verizon UML290 3G/4G wireless USB modem

1. Can I achieve our goal with the equipment and WAN connections above?
2. Is there a another method that may accomplish the above? Any suggestions welcomed!

The Sonicwall is the desired device due to the ability to implement Gateway Security Services.

Thank you,

Hi Experts

We had one of our 3750's hardware fail, will not power on. Were currently purchased a new 3750 to replace. Would like some general guidelines on the steps to do so. the most important we want the vlan information to come across.
Do we backup the config on an existing switch and apply it on the new one? - We tried and received a lot of errors
Do we apply the vlan and other port information (below is our existing) to match what we already have.
How do we place the switch back in the stack, unpowered and connect all the stacking cables and then power it on?
What Impact will that have on the stack, will it power down?
What will and will not come across after we add the switch to the stack, do we need to set a password on the new switch, I know after you add the switch the master takes over and it applies some information - firmware.

The switches in the stack has a lower SW Version than the new switch being added will it be downgraded automatically or something we have to do manually.  (sw version of the switches in stack 12.2(25) SEB4 \ New Switch 12.2(55)SB

interface FastEthernet1/0/12
 switchport access vlan 10
 switchport voice vlan 20
 srr-queue bandwidth share 10 10 60 20

I suspect I bought the wrong thing and I need advise on how to do this right.

My network is a mixture of Cat 5 and Cat 5e cable connecting student and teacher workstations. As we move into the future, I thought this would be limiting our data flow.

I bought 1000 feet of Cat 6a solid core shielded wire. It is twice the thickness of the cat 5e and clearly will not fit my normal RJ 45 jacks.

Can I use what I purchased somehow?

If not, what do I need to get?

Should I just stick with the Cat 5e that I have?

Thank you.
Please do you have an answer for my situation?

I have already added our printer (Samsung) and I am deploying through GPO which works fine. However, when I have added the Fax Utiliy (Which sets up as a seperate device) this does not deploy. I tried to add the Fax Device manually on a client machine and I am prompted to install drivers. I click "install" and it fails with the error 0x000003e3. I believe this is why the GPO is unable to deploy the fax service.

The fax service is on the same IP as the printer object so I cannot add it using LPT1 with IP address as this is in use by the Printer function. I have to create a Samsung Network PC Fax port.
How can I configure this so that users are not prompted to install drivers that then fails with the error? I believe I will then be able to deploy through GPO to my users.

Many thanks

Need to run direct burial CAT5E with telephone signal lines and intend to terminate with RJ11 plugs.
I find that the wire insulation diameter is a bit large to assemble the cable end into the plug.  
I suppose that I could terminate the CAT5E cable with a modular jack and then use a telephone cord (RJ11-RJ-11) from there.
Yet, the same issue isn't anticipated on RJ45 plugs.
Is there a wire diameter (including insulation) specification for RJ11 that's smaller than for RJ45?
Hi, the title said it all. Can anyone draft me some pros and cons of stacking switches?

And is it possible to simulate this techniques in GNS3, Packet Tracer or something else?
I have a security camera project that requires a run of about 1000FT for a few cameras.

I know Cat5/6 are not options due to the 300ft limitation.  I guess I could use POE switches at 300/600/900 ft as repeaters but that doesn't sound like a viable solution.

any ideas?
When you use NIC Teaming do the NIC have to be connected to the switch?

I'm buying a NIC card to add to our server and they come in 2 or 4 ports.  Do all ports have to be connected to the switch to Team them?
I updated one of our supermicro servers to windows 2016, i have the onboard network causing problems (Motherboard SYS-1027R-72RFTP), is a two port network card and it keeps showing me like 8 cards, they dont work, and i have downloaded the drivers from supermicro for 2016 and still i get the same result. Any help will be appreciated.

Can anyone help me configure the cisco for ppoe???

Trying to set up internet for home use with the ability to fail over to a second internet connection (such as cellular). Since my phone and security system are both internet based, I just want to see if there is a (cheap) way to ensure device connections stay up if the primary internet goes down. Since the phone and security devices are not tied to a particular external IP, having them suddenly move to a different external IP is not a cause for concern.

I know best practice for business is to fail over to a different ISP, but since this is for home use I'll say that isn't required here.

I'll figure out which ISPs later. Right now just looking for hardware recommends and how it should be configured.

Does the HP 2910al-48g have this functionality?

I've looked in the manual and can't find anything regarding that. (Maybe that means the capability isn't there?)
We are being told by an outside technical consulting firm that we cannot upgrade servers until our entire network infrastructure has been replaced.  I need an experts opinion on the scenario and comments made by them (below).

For reasons too lengthily to go into here we are still running our internal domain on W2K3 servers. All of the desktops and laptops are "newer" machines running Windows 7 or 10.  We vertualized the BDC's and member servers 2 years ago but are still running the PDC on old (ancient) hardware.  The new server we verualized the other servers on is intended and capable of running a new domain (built from scratch) on Windows Server 2016.

Our current network infrastructure is built on Cat5 cabling installed circa 2001 and our switches are 10/100 with gigabit dual mode (62.5) fiber up-links. These are old and due for replacement also. Our facilities are spread out through several buildings nearly a city block long.  We have obtained quotes to rewire with a combination of single mode fiber and Cat6 cabling to the desktops, WAPS, etc. Those quotes came in around $100K which is some pretty bitter medicine to swallow at this time.

I suggested to the consulting firm that we move forward with the switch replacement using single mode capable units that we can configure to 100Megabit on all ports and proceed with the domain server upgrade.  Their response was as follows:

"we need to have a solid infrastructure in place in order to put the best
Trying to figure out if I could use one of these new wi-fi mesh router systems in 10K sq ft office.  Wi-fi coverage is sometimes intermittent - using a Sonicwall TZ215 router and Tp-Link PoE hub with 2 additional tp-link EAP 330 access points.  Advantage of the Sonicwall router is antivirus and firewall.  
Advantage of the wi-fi mesh systems (eero, Velop, Orbi, etc) would be the complete wi-ficoverage.  Is the firewall in these good enough?
If not, what would be a good alternative?

Configuration Raspberry Pi 3 with camera
QNAP TS-453 Pro

I have a Raspberry Pi 3 up and running with the help of this image:
The guy who developed the image has a blog where he describes how to connect the Raspberry to Survellance Station:

I tried it and can connect to Surveillance Station, using these settings:

Camerabrand:       Generic Model
CameraModel:      Generic RSTP
Cameraname:        Camera 1
HTTP URL:              /
IP address:   
Port:                        80
RSTP Port:              8554
Username:             <empty>
Password:              <empty>

When I use the rstp url in VLC, it works great: rtsp://
On Surveillance Station, every now and then the connection works, the camera in connected and I can see what it's filming.
After less than a minute the camera is disconnected.

For now it looks like the only times I had a successful connection when I played the stream in VLC as well....
But I can not reproduce that, because it's not working this way every time....

What could be the cause of this ?
my career growth which course i will study?
I have dell poweredge r710 with below hard drives:
3 - 250GB 7.2k SAS
4 - 600GB 15k SAS

I was thinking this raid configuration:
3 - 250GB 7.2k SAS on raid 5 (this partition to install ESXi 6.5 host)
4 - 600GB 15k SAS on raid 6 (this partition as datastore for VMs)

Is this recommended or there is something which can be done better? Please advise.
