Please take a quick look at this Aruba WAP design and let me know if there anything can do better there.  Or if there anything I should change.
Are the Aruba controllers HA with a heartbeat cable between each other or over the switch?
I will have about 10 APs.  
Does it make sense for x2 Mobility Masters in different geo locations?

Any  other tips please let me know.  Thanks!

Free Tool: Subnet Calculator

The subnet calculator helps you design networks by taking an IP address and network mask and returning information such as network, broadcast address, and host range.

One of a set of tools we're offering as a way of saying thank you for being a part of the community.

I'm working with a HP Pavilion P7-1414 running Windows 8.1. The computer currently has a Ralink RT5390 wireless card that comes with the computer.
After you connect it to wifi and start browsing, the machine will either bluescreen or freeze. If it bluescreens, according to the program "whocrashed" it's a DPC Watchdog Violation error and has been referencing two different system files: hal.dll and ntoskrnl.exe. I have installed a brand new Startech PciE 300n adapter (PN: PEX300WN2X2) and discovered that is also uses Ralink drivers, and will also bluescreen or freeze the pc after connecting to wifi and browsing. I have tried about three different versions of Ralink drivers on both devices and all will result in failure.

Here's the curveball, I have a USB realtek wifi dongle that I installed, confirmed it was using Realtek drivers, and it is NOT crashing or bluescreening the computer after a couple hours of testing.

Any suggestions as to what's going on? Is it underlying ralink driver corruption or perhaps a registry issue? Issue just started happening on Monday the 15th, and the customer suspected it might have been a Windows Update. I checked the update history and saw where there was an attempt to upgrade the Ralink Driver a few days prior to monday, but reports failed. Don't see any other updates that could be affecting it.

Hi - i need help setting up a guest wireless network on a different subnet from the work wireless network.
We have 2 D Link AP's that have the ability to have up to 4 SSID's with different VLAN's, DHCP is coming off a Windows 2008 server and all are connected to a Netgear switch that has VLAN capability.
Please can someone help me with this setup - is it even possible to have a separate guest subnet with this setup?
Thanks

Has an old router B with guest network feature that would like to convert to an access point, whereby users can connect to the guest network from router B. Router A the main router is an Asus router and Router B is a TP link router
Followed the instructions from the below link..
Able to connect to router B normal WiFi ssid and surf web and at the same time it’s able to access internal net work resources.  when connect to the guest network, it shows no network connection.

https://www.google.com.sg/amp/s/www.cnet.com/google-amp/news/how-to-turn-an-old-wi-fi-router-into-an-access-point/

Saw another link whereby this can be achieved when router A is using the dd-wrt firmware
https://www.howtogeek.com/153827/how-to-enable-a-guest-access-point-on-your-wireless-network/

Is there ways to configure when router A is not using dd- wrt firmware and users can get connected to router B guest network?

Hi,

In our lab I have 5 identical desktop computers with a wireless network connection (all same brand/same model/same software/bought on the same date)

We normally connect to these using RDP.  4 of those work absolutely perfectly. The 5th has a weird problem:
If I connect to this desktop computer using RDP and start a ping -t servername in a command window (on that desktop computer), every 10th ping either gets a "request timed out" or has a very high (>3000) time value while the others typically have 2 or 3ms.  This results in serious lag when using our engineering software.

What could be the problem? Anyone have any ideas?

I have a Dell Latitude 5414 Rugged laptop with internal cellular with the following problem:

The cellular card stops responding to pings when an ethernet or wifi connection is established.  This is not a routing issue but rather a windows 10 issue where it disables the cellular card when it detects another connection.

I have tried all the standard troubleshooting, updated drivers, changing network metrics, powershell hacks and many others but nothing works other than downgrading windows 10.

This is causing a problem for me because the machine needs to have a camera system connected to the ethernet port while connected to cellular.

This problem began with windows 10 version 1709 and is not a problem with version 1703 or earlier.

I can also confirm that the Windows 10 mobile hotspot feature does not work ether because of the same problem.

Can anyone else confirm the problem with their laptop with built in cellular?

The cellular card is the dell wireless 5806e gobi 4g lte.

Thanks!

Does any know if Aruba will advertise both 2.5 and 5Ghz band with the same SSID? There are three APs total for example and they are are part one one IAP group with one acting as primary.  The user can act has 2.5 or 5Ghz?

Also, is there a good tool for running a heatmap for these set up? There is no controller.

TIA, LN

Hi there,

I have a 2504 WLC at a remote site overseas currently on code 8.3.121.4.  I need to update the code on it due to the KRACK vulnerability, but wasn't sure what the best route was to go on this. Cisco's suggested release is 8.2.166.0 (ED), but I'm hesitant to downgrade the code as I've heard some horror stories (losing configs, etc.) and I don't have an onsite resource there in case things to to hell.  Cisco TACs recommended 8.3 release is 8.3.133.0... would I be better off just upgrading to that version instead?  Would that be safer for a remote update?

Any input is appreciated, thanks!

We have been tasked with connecting a room to our corporate network via wireless router.  I am not that adept at wireless security.  Can anyone give me any general guidelines to make this as secure as possible?  Is this even recommended.  Our domain is a Windows  2016 domain.  

Thanks

I'm looking at some of the above: anyone know if the one with 3km distance has good penetration against 2 layers of walls
(each layer of about 15cm thick)?

I'm placing a wifi router with a camera in my car & from my office which is about 500m away, I want to be able to connect
to the camera to monitor the car (from vandals) from my office PC.  There could be 1 to 2 layers of walls in between.

Feel free to recommend any other products.  Don't need encryption, only good distance/penetration

The price charged for Aerohive POE injectors suggest they are made of some rare and precious metals (gold or platinum perhaps) and come with a free date with GOT's Emilia Clarke.

GIven I dont have the money and have a wife that would rule out the date with Emilia Clarke does anyone know of a compatble POE injector with Gigabit.  They run 802.3at :)

Hello!

I'm working with a small business (5 employees) that work out one building that is separated into two offices by a fairly heavy-duty wall.  We have wifi in one building (using a consumer-grade wireless router), and would like to add wireless access to the other office, but only a very weak signal bleeds through.

I know that I could add a wireless router to the other side, set up with the same SSID and encryption/passphrase, and have it work reasonably well... however, in the past I've run into issues where a device on wireless 'A' doesn't let go of the signal and grab wireless 'B', even though B is stronger.

I contacted our CDW rep to find out what a base SMB solution for this type of scenario would be (two access points that support roaming, without a controller), and his best solution was a couple of Meraki MR 33 access points, at roughly $450 each.

$900 was more than the boss wanted to spend... does anyone know of a more cost-effective solution for an SMB?

We currently have MaaS360 and want to come away from that due to the limited functionality and lack of helpful features. We would require something that provides more control over the device. So that we can allow and restrict apps as necessary.

EDIT: We also push 3 apps currently and would require that feature as well. Something does a fairly good job at auditing the devices within the company.

We have a c3750-48PS the switch works fine on the computers, but the Access Point doesn't come up, it lights up, but it doesn't see the Wireless Controller. The Access Point is a 2802I.

Any ideas?

I'm a developer by trade, but when it comes to any kind of networking issue, I'm a pig on roller skates. Here's my dilemma:

I'm considering eliminating my TV cable service and making my television viewing entirely Netflix etc. In other words, I want to go with either the Amazon Fire Stick or Apple TV. Both of which require solid, consistent internet service.

At this point, my WiFi is not especially good. By that I mean, sometimes when you go to access Netflix, you'll have to restart the Wii in order to properly connect. Another example would this morning I was ordering some tickets and suddenly, the internet quit. By that I mean the connection was interrupted.

First off, how do I test the quality of my signal? I've read some about some apps that I can download such as "Network Analyzer Pro" and others. What do I need? What do they do and what conclusions can I draw from their readouts? However obvious those questions may be, what I'm wanting to determine is whether or not these apps will tell me whether or not I need a new router.

Secondly, what is your take on the Amazon Stick vs Apple TV?

Finally, do I need either of those devices if I purchase a smart TV?

Bottom line: How do I diagnose my WiFi and what's the best approach to take if I want to eliminate cable and pursue a purely internet based programming for my TV viewing?

Thanks!

The place I park in office is about 200-300m from where I seat:
I can't see the car as blocked by walls.

My car is parked along the street which can get vandalised (scratched, etc):
I wanted to be able to view my car from my office PC/laptop (or at least from
my iphone) remotely : the street is a straight one & if I sit in the car, I could see
if someone is approaching (even >100m away).

Anyone has any solution to this?  I don't want a recorded video as it's too late
& the vandal would have taken place.  I wanted a camera/device which will make
it like I'm viewing from within the car (but I'm viewing from my office seat).

Feel free to show me any eBay/Amazon links of the items you recommend.
Not something more than US$300 ideally.

I have an iPhone 4 and an iPhone 6: perhaps one of them can be mounted in
the car (with a low-cost 4G data plan of US$20/month for 20GB data)?  If it's
something that don't need any data plan, will be better but I'm Ok to get one

Question regarding an enterprise wifi GPO policy.  I have created a policy and it has successfully pushed down to 25+ Windows 10 tablets.  Only one of those tablets shows that "Some settings are managed by your system administrator" when checking the WiFi config which is good.  However, the other tablets do not show this and thus allow the user to tinker with the settings if they feel led to.  I have confirmed that via gpresult that all tablets have successfully received the GPO.  Any idea why these tablets are not locking down the settings like the one I mentioned is?  Thanks!

I am tasked with upgrading an office/warehouse WiFi.  The office area is approximately 2500 sq. ft on main floor, and 1100 sq ft on 2nd floor.  The remainder of the building consists of 3 warehouse areas: 2 are approx. 2750 sq ft ea, and the 3rd area is approx. 5500 sq ft.  8-10 users in the office and 10-15 users in the warehouse that come and go all day.   Traffic is primarily Port 80/443, email, and smartphones.

Am looking at 6 A/Ps: 3 in the office (2 on 1st floor, 1 on 2nd), and 1 in each of the warehouse areas.  Am considering TP-Link EAP330  to accommodate the client's budget, as well as Aruba IAP-305.  

Does anyone have familiarity with either of these and why you would select one over the other?

Thanks for your input.
