Sony Vaio all in one pc wireless adapter cannot get higher than 65 Mbps even though the computer is in the same room with the network wireless router.  My much older laptop gets 300 Mbps on its wireless adapter.

How can I speed up the Atheros AR9285 wirelss adapter on the Sony Vaio computer to go higher than 65 Mbps?

Thanks for your help in advance.
Our Windows 7 workstations are not authentication wirelessly. When we ask users to hardwire in they connect fine.
Windows 8 and Windows 10 are fine.

My teammate confirm certificate is not expired and from what we were told by another group no changes were made to Group Policies for WIndows 7 OU

Please see logs I am seeing on Windows 7 PC

Hello, I have a customer PC which behaves in such an incomprehensible way I had to post it here.

Here's the facts: it's a desktop with Windows 10 and a PCI wifi card.

Wifi used to work, now it suddenly has stopped. It will connect and receive ip and dns through dhcp, but won't even ping the router.

And here, the strange stuff begins: I tried in my office and it worked. Cleaned it up, reset winsock and tcpip, brought it back. Doesn't work.

So I tried with a usb wifi adapter. Same behaviour.

I decided to format and reinstall Windows 10. And here's what totally blew my mind. Now it has the same behaviour in my office too, with the usb wifi adapter (still haven't tried with the pci card). It's a frakking fresh install for criminy's sake!

I honestly don't know what to think.
Over the weekend we needed to power down our servers for some building testing. After booting everything back up, one of our SSID's that use RADIUS was not working. The logs didn't show any issues so instead of wasting anymore time on it (I had spent 2 hours on it) I decided to uninstall the NPS role on the server (dc01) and decided to install it on our second server (dc02). Upon installing it, I tested everything and it works. Both on my phone and laptop.

However, coming in this morning. There are a couple of end users that state they are unable to connect to the SSID that uses RADIUS via Laptop. I check the logs and it states
Authentication failed due to a user credentials mismatch. Either the user name provided does not map to an existing user account or the password was incorrect

Open in new window

They are able to connect with their phones with the same credentials. Some are able to connect w/ their laptop (windows 7). All macOS are able to connect.

Currently in my home, due to a thick concrete wall, the corner when my bed
& reading desk is located can't reach the broadband Wifi even if I connect
a Vonets VAR11N repeater below to the Telco's Wifi router:

I then used a USB Wifi dongle plus a 6m USB extender cable to connect to
my laptop with dongle bypassing the thick concrete wall (with direct line-of
-sight to the router) & could now consistently get the Wifi signal:

However, for my iPad & my Android phone (which sometimes I read on the
bed), is there something equivalent to the Netgear dongle that I could use
with a USB extender cable?  Ideally one solution for both iPad & Android
instead having to buy separate solutions.

I ever seen a metal sticker which claims that once pasted onto the phone
will enhance the range of mobile phones' but lost that article : does this
work & can share an eBay/Amazon link to purchase?
I recently replaced my older DOCSIS 3.0 router with an Arris SB8200 (XFINITY compatible). The connection works on my Mac Book Pro but when I connect my Asus RT-AC86U to it, I can't connect any other devices and the internet LED is red. I need to get wireless from the Asus up ASAP. Please help. Thanks.
Cisco 5520 Wireless Lan Controller unable to connect access point using wired connection using POE injector using CDP I can see access point but unable to have it show up in access point list.  The access point is directly connected to WLC, with no switch or router but both AP and WLC are using ip in same subnet /24.
ISE Express Wireless ScreenshotSetup

In setting up ISE Express Wireless Setup, does the "Wireless Express Setup" needs internet connectivity? I am having this error message says "At this time, Wireless Setup is available only on re-login. Please click OK to re-login or Cancel to dismiss."
What is the most reasonably priced captive portal router/ap or just Access Point?  The owner should be concerned about segmenting network from guest traffic when utilizing the captive portal feature.  I was thinking Sonicwall TZ series for traffic segmentation.  I'm not sure if the integrated wireless does captive portal feature or simply get a Ruckus for the wireless part but then the pricing quickly gets expensive.   Another more hooptie solution is a daisy chaining the primary and purchasing a cheap router/AP solution that again has the Captive Portal feature.  However, I'm not sure how much perform degradation for both the business and the guest segment would be.  Thoughts?

Laptop with Windows 7 Pro. I am trying to connect to a wireless network that I have connected to in the past. The SSID shows up in the list of networks long with several others in range. When I try to connect I continually get the message that Windows Cannot connect to this network. I have reset the wireless adapter, updated the drivers, uninstalled and reinstalled it, updated the BIOS and even tried a different wireless card (a USB dongle). I have also run to netsh commands to reset winsock and the catalog. I also removed the network from the list and tried entering it manually. Nothing has solved the problem. I can connect another laptop (same model, same O/S) to this SSID, as well as my cell phone and tablet. Please advise.

Thgank you!

I'm exploring the use of drones to do delivery (for items that weigh up to 20kg
ie about 44 lbs) of dimensions up to 2ft long x 2ft wide x 10 inches thick.  

Once local authority approves it, thought of sourcing/purchasing some of these
drones but will need to look into the cost effectiveness (ie its  gasoline/petrol
costs, maintenance/repair) or is there any that uses rechargeable powerbanks?

Has Amazon or any country done it & what's the safety & regulatory requirements?
Issue with Apple users for Aruba virtual controller

http:/ sites are not trusted and as Apple users  have no choice about the connection.  Android users have the choice to accept or reject.  For the Apple users (all types) if I open safari and put in arubanetworks.com the browser will show the site and allow the connection.

Any ideas on how to sort this for Apple users?
Fortigate 200D in HA cluster

i have a problem (user "accidentaly started wizard" to change gateway)....

and fortinet stoped routing as expected, as it seems nothing has changed.
static routes are the same as before, route lookup hits the right route, traffic seems to hit the right policy.

Monitoring the traffic it says       "Accept: session timeout" for everything

i can ping port to internal network from CLI, i can ping something on Internet (WAN) from CLI

but nothing gets thru from external(WAN) to internal network (PORT1) or viceversa
We’ve enabled Microsoft MFA for our Office 365 Accounts (aka.ms/MFAsetup).

I remain a bit unclear as to how frequently it’s supposed to expire and require a fresh text code.


1. Does it matter if I switch between Starbucks Wifi and McDonalds WiFi?  We have it setup so it never asks for MFA if you are on OUR internal WiFi network.  If I’m not on OUR WiFi, does it matter WHICH WiFi?  Or, is the fact that I'm switching between work Wifi and non-work wifi, is that causing issues?

2 How long should it last?  I believe if using a web browser, there’s a checkbox to ‘don’t ask for 60 days’.  However, if I’m using the Outlook App on a laptop, it doesn’t offer the 60 days.  How frequently is it supposed to ask?

A user was on vacation and was using Outlook on a Surface just fine.  However, as soon as she went on the airplane (American Airlines), it immediately wanted MFA.  Any ideas why?

Thanks for any clarifications,
Mirror Apple TV on iPad Pro to view MLB-TV

MLB-TV with iPad Pro (iOS 11.4.1) consistently loses WiFi connection with LAN (44.7 mbs / possible 50) iPad rebooting necessary.

Is it possible to mirror Apple TV (MLB-TV OK here) with iPad Pro/Control Panel to view MLB-TV on iPad? Other folks will be watching TV on cable or Netflix/Amazon Prime. This is the reverse of screen mirroring (see Control Panel) as in viewing iDevice on Apple TV.

If so, are there special settings etc.?
Which cellular carrier has the best coverage?
There's a lot of marketing that says Verizon is the best.  But is it really?
And how about the super-cheap cellular services.  Which carrier are they using.  Surely the smaller brands don't have their own network backbone.

Another wierd observation!  Some people are able to surf the net on their smartphones in the NYC subways, others can't!  The transit authority WiFi ain't that good.  So, its gotta be the cellular carrier.
I appreciate links to useful studies, articles, or videos.
We have a ubiquti wireless bridge in the office connecting to another ubiquiti wireless bridge in the yard and connected to that bridge is a wireless access point (have tried ubiquit, tp-link, netgear) and none of the access points is passing dhcp traffic once a single connection has been made (ie it won't allow more then one dhcp client).  We have even tried static ip addresses on the clients in the yard and they will not connect to the access point and will continue to say the wireless password is incorrect.  As soon as we take that one connection off we can then connect a different device.  DHCP is running on Windows server and the gateway is a watchguard firebox router and the wireless bridge in the office is hooked up to an HP procurve switch that was set as access and have tried trunk with no success.  Any thoughts or suggestions?
We have a computer that shares it's wifi using Windows 10 'Mobile hotspot'.  The ba d part is that every time the user logs in, has to enable it.
Is there a way to enable 'Mobile hotspot' automatically when user logs in (see pix below).

Cisco-AIR-AP1852I wireless antennas turned off. But to configure Cisco Wireless Mobility you need to turn them on to access the default page. We have 20 AP's and I can't get any of them working. Please help. I am with a Non For Profit - Hope Foundation in South Carolina serving autistic children, and we do not have a Cisco support contract because they are expensive.

I dont have too much experience with VLAN Tagging so need a little help,  I have a Draytek Router and a Draytek AP, I have setup a Wifi Network for Staff which goes through LAN1 which works fine through both the Router and AP, I've then got a Guest Wifi network through LAN2 using a VLAN Tag of 10 which ive set on both the router and AP, the problem is there is a Netgear Smart Switch in between which I think is stopping the tagged traffic and I'm not sure how I need to setup the Netgear to allow the traffic, the guest network works fine on the Router but not on the AP the devie thats connected cant get an IP address from the DHCP Server (Draytek Router),  The router and AP are setup as follows: (Just in case you cant open the link I've also put pictures from the guide as you need a login to see the page)


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
I have a LAN point only in a reading room (that enables my laptop to
connect to Internet).

Is there any way that I can make this laptop an AP (without buying
extra devices, ie no AP router etc) to make this laptop a Wifi AP so
that other PCs/laptops/phones could connect to it to access Internet?

I could consider TPLink's device below but the piece I just got online
(from China) could not even be detected by Windows but I need to
get this thing up quickly:

The laptops I have are X230t and X61 with wireless modules  built into
them so I'm wondering if there's softwares to make the laptops to have
wifi 'tethering' function.

Let me know also if I need to configure the laptops windows to make it
 a router (by adding persistent routes) using
  'route add -p ... '
We have Ruckus wireless network and I have 2 working  SSID.
SSID-A is on VLAN 81
SSID-B is on VLAN 82

My predecessors had setup a NEW SSID which is on VLAN 83  and it is not working.
When I connect my laptop to SSID-A or SSID-B it gives the IP address from that particular subnet.

If I connect my laptop to the NEWSSID, it says limited activity with yellow exclamation mark and gives APIPA IP address.
There is a trouble shooting option with the Ruckus wireless controller using a mac address of the laptop and when testing the DHCP request fails and It looks like the NEW SSID is not set up properly to reach the DHCP server.

So our edge switches are POE Cisco switches and I would like to see the edge switches if they are set with DHCP helper address for VLAN 83
Please let me know the cisco command to view the VLAN configuration of VLAN 83 .
Or let me know if there is any better way of trouble shooting this issue.

Thanks and any help will be great.
When I change the wifi channel on a Draytek VigorAp 800 it stays on channel 6.

I have a VigorAp 800 that shows on its Wireless LAN >> General Setup page that it is operating on Channel 1 with Channel 5 as the extension channel. However the channel used by client devices is Channel 6. However I change the maion channel on the AP, everything stays on channel 6.

I'd like to change as a neighboring SSID is also using channel 6 and is quiteb powerful.
