I am looking for a tablet/laptop that employee can use when they are on the go.

I will have an access program running on it [the database is on the company server].

Need to connect to their office computers in a domain environment via a VPN connection.

Light work [no robust system]

Work on Verizon network.

Purpose of porches giving the employees access to their computer on the go and using the access program.

Any recommendation, please.

what are some of the small business routers that will be recommended to come with guest wifi, vpn plus range of security features?

Just received the Vonets device & tried the above suggestion of setting it to "Bridge + Wifi repeater"
followed by steps in page 7 & 8 below:

Q1:
I'm able to use it as Wifi repeater ie by placing it say 12 ft away from my Wifi broadband
router & with my laptop is a 'blind spot' of my bedroom, my laptop could connect to that
device "wifi hotspot" & get to Internet (which previously my laptop cant get to Internet).

Now, the other requirement as per the original enquiry in the EE link is to connect it to
a LAN port & serve as Wifi hotspot: can't get this working: when laptop tried connecting
to this device's SSID, it prompted for password which when I enter, it simply gave the
message "password not right" though without connecting this device to a LAN port, the
very same password works.   I've tested connecting the built-in LAN cable to LAN port
OR (ie one at a time) using a LAN cable to wire the WAN port of device to wall's LAN port.

Q2:
If this works, the next thing I'll need is to connect this device to my laptop (while my
laptop is connected to a LAN port on wall & serve Wifi hotspot to others

Q1:
I'm looking for installation/setup manual as well as driver for
VONETS VAR11N-300;  refer to link below:

Q2:
Saw somewhere that in a hotel room's wired LAN port (RJ45), just have to
plug this device into the LAN port & power it up & we'll get a Wifi SSID
in the hotel room?   Is this so?

Q3:
If it serves as AP-client as in Q2, I suppose we won't need a driver, right?
if so, can I plug it into my laptop's LAN port & the laptop will become
accessible or the laptop will act as a router??

How can we compare the range or performance of 1 specific HP access Point vs 1 specific Aruba Access point.

At m y work we are planning on migrating from an old HP System that is using:
- HP E-MSM466
- HP MMO 6 Antenna J9659A


To a brand new wireless infrastructure that will be using Aruba Instant AP-325
http://www.securewirelessworks.com/Aruba-IAP-325.asp

My question is: How can we judge the range that the new wireless AP will spread to vs the older model?  

From what I have researched it is stated that the ranges differ by country.  That makes sense because I think that the power provided by the AP will help determine the range.  Different countries have different power standards.  But, if that is the case then theoretically speaking there should not be any difference between the range with the older AP's and the new AP's.  How can we tell?

Aruba is suggesting to add more APs than what we currently have in place(with the older system); but we want to compare the 2 and research what the expected.  Right now we are hoping to do a 1 for 1 replacement regarding wireless access points.

After reading all reviews for above device at Amazon, I'm uncertain if it could meet my requirement below:

I have a home Set-Top box (from Telco) that connects to my broadband router via a wired (ie RJ45) LAN cable to stream movies (such as Netflix etc). How can I use this device so that family members can view the movies from their laptops in bedrooms?   This Set-Top box has an RJ45 LAN port, an output HDMI port that goes to TV & a USB port (which I'm not sure what's the USB port is for).

Currently from the bedrooms (can be 5m to 30m away from the broadband router which has wired RJ45 ports as well as Wifi), we can't view the movies/streams via the broadband router & one bedroom barely can connect to the broadband Wifi

hello experts

hello experts
i have 3 SSID configured on an autonomous Cisco AP, all authenticate against ACS server, so three policy for each SSID, i did configured DNIS as *WIRELESS_SSID in "End Station Filter" but looks like it only works for WLC not autonomous AP, and seem Cisco autonomous AP not sending SSID info to ACS while the processing of authentication, my question is how to make Cisco autonomous AP to do this, i did try the following:
radius-server attribute 32 include-in-access-req format %h
radius-server attribute 30 original-called-number
radius-server vsa send authentication
but it doesn't help, please give me your suggestion.
thanks

Hi,

We have a dedicated 100Mb fiber connection and I am looking to upgrade our current wifi.

The building has two floors. The office warehouse is on the ground floor and the main office is located on the first floor.

I want to put a business graded wifi router that can support up to 30 devices. Can someone recommend a decent wifi router? I think I just need only a good one for the whole building.

At my gym they have Wifi.

When I go on the treadmill, I watch music videos on my iPhone 6 Plus and listen with my Jaybird Run bluetooth earbuds as I run

Is that not a good idea?

What I mean is, if someone gets on the treadmill next to me can they use their phone to hack into my phone through the wifi?
I'm kind of paranoid of people with all the crime these days.  
So when some dude gets on the treadmill right next to me even though there is a bunch of treadmills everywhere not being used but they still get on the one next to me that seems weird to me. Am I just too paranoid?
What do the tech experts do when they go to the gym?  Do you guys use the wifi or phone's internet connection?

Should I just turn off the Wifi on my phone and just use my att phone's internet. I have the unlimited data plan anyways.

I have a kyocera Ecosys FS-C2126MFP+  is there any way to make it wifi enabled ( thru print server etc)

Hello and Good Evening Everyone,

          I am getting ready to purchase an Amazon Echo (2nd generation) and wish to know the pros and cons of it.  The one which will be ordered is at https://www.amazon.ca/Echo-2nd-Generation-Charcoal-Fabric/dp/B0749ZSPN7.  That said, could someone share with me your thoughts and experiences with it?  It will be most helpful to me as I enthusiastically await to make this purchase.

          Thank you

          George
