Massive difference between wired and wifi speed fr...

Our new wired Home hub is delivering around 36 MBPS but on wife is only getting 25... I know we lose some but this is ridiculous! Any thoughts a to why please?

There are many reasons for slower speeds on wireless and that is the reason that all ISPs will not guarantee speeds on wireless. Your speed difference is probably better than most.
Speeds can be effected by interference, distance from source, standard of receiving device, construction of property walls floors etc,
Some things you can try to improve it is check that the wireless card drivers on your device are upto date. Use the card manufactures website for that.
Download, install and run inSSider. It will show you the wireless channels and which one your Homehub is on. You want to find the channel with the least congestion, ie. least number of users. Once you have that you need to change your homehub onto that channel.

Why such a huge difference between wired and wi fi...

Hi,
I'm on Infinity with a curved Home Hub. I get speeds of 38 down and 8 up from a cabled connection to the hub and speeds of 18 down and 8 up on wi fi.
Why is there such a massive difference in speed between wi fi and wired?
I get the same result with the laptop sat next to the home hub over wi fi so I know it's not because of walls etc...
I've used inSSIDer to check I'm not using the same channel as anyone else.
I'm losing 20 meg thingys somewhere, I want to know whose got them!

Got the same one, yes its built in and as could be swapped with this
Might need a Computer shop or tursty geek to swap it out for you.

WRT54G2 v1 - Substantial Speed Difference Between Wired and Wireless Connection

Hi everyone,
I have a WRT54G2 v.1 router connected to an RCN Cable Modem. My download transfer rate direct from the cable modem is 18 Mbps. Thankfully, I can get the same download rate when I plug my laptop into a wired ethernet connection from the router. However, the wireless connection only gets a download rate of 0.8Mbps. Also, my wireless card is pretty new (Intel 4965AGN) and has the latest driver (I can get far higher download rates at mobile hotspots, for instance). Here is what I've tried with the router:
- I've upgraded the router firmware to the latest build (Version 1.0.04, 07/08/2009).
- I've tried multiple channels on the network (1, 6, 11).
- I use WPA Security.
- Upon advice from the Linksys live chat support, I've changed the MTU settings to manual and set them to 1300.
- They also recommended that I change the following settings: “RTS Threshold” – 2304 “Fragmentation Threshold” – 2304 “Beacon Interval” – 50
- And of course: I've got my own SSID. The router is 5 feet off the ground. There are no other wireless devices that would cause interference. The router is not near large metal objects, fish tanks, or any other physical obstruction.
Is there anything else I can do? Thank you so much in advance for reading. I really appreciate it.

Also, is there anything to the fact that only the download rate seems to change?

Difference between 38mbps and 76mbps speeds

I was wondering that if im getting around 25-30mbps download on infinity 2 76mbps package would i get the same or roughly the same download speed of 25-30 on the 38mbps infinity 2 package? No point paying for 76 if im getting nowhere near that speed

Downgrading to Infinity 1 should not affect your speeds if 30Mbps is the max you can get.

I understand the difference between imessage and SMS but when I text a friend who always got iMessages in the past, everything I send her is SMS (green) even if we both have wifi. She has an iphone.

I understand the difference between imessage and SMS but when I text a friend who used to receive imessages (blue), my phone shows I'm sending her SMS (green) messages. No longer are they blue. She has an iphone and this happens when we are both connected to wifi. We have both recently updated to ios7. Thanks!

Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

The NEW macbook Pro and Air are EXTREMELY close in form factor
The newest macbook Pro is essentially a larger macbook Air with Retina display and options for speed in increasing prices up to an independent graphics and quad core processor.
both Air and new Pro now have PCIe SSD and permanent RAM.
The Air is the lightweight portable form factor, fast to boot and shut down, but with longer battery life than any of the macbook pro in 13"
Now the new macbook Pro and macbook Air are extremely close in form factor and nature.
both have 802ac wifi
both have permanent RAM, no superdrive
both are slim profiles and SSD
The only real differences now are (in the most expensive Pros) faster processors and quadcore processors and top end model autonomous graphics.
....and of course the retina display
both are now "very good for travel"
Other than features the form factor of the Air and Pro are VERY close now,....so now its merely a matter of features and price more than anything.
You need an external HD regardless of what you get for backups etc. Drop into an Apple store and handle both and make your choice based on features, such as Retina or non-retina, .... both at a distance now look like the same computer.
The Pro weighs more, ....but nowhere near what it used to just a month ago on the older macbook Pros
The NEW macbook Pro is a different creature entirely than the older macbook Pro, .....the new Pro is thicker than the Air, but id frankly call the NEWEST Pro a "macbook Air with Retina display" , or
Maybe a “macbook Air PRO with Retina display”
Instead of Air VS Pro now,.....its really a smooth transition from Air to pro without comparing say, 2 different creatures, now its like contrasting a horse from a race horse.
Either one in 8gig of RAM (preferably)... the 4gig upgrade costs very little, the I7 you will notice only 15% faster on heavy applications over the I5, and NOTHING on most APPS.....I5 has longer battery life.
As you see below, the non-Retina 13" AIR is 82% of the Macbook with Retina display in resolution
there is no magical number of pixels per inch that automatically equates to Retina quality.
http://www.cultofmac.com/168509/why-you-might-be-disappointed-by-the-resolution- of-those-new-retina-display-macs-feature/
A huge internal SSD isnt a game changer for anything, you need an external HD anyway
what you WONT READ on Apple.com etc. is that the larger SSD are MUCH FASTER due to SSD density
"The 512GB Samsung SSD found in our 13-inch model offers roughly a 400MB/s increase in write speeds over the 128GB SanDisk/Marvell SSD"

WDS wired and wifi with mixed airports

Hi,
I've been having a heck of a time with 'fixing' a mixed wired and wifi network. 2 days so far and it's still not how I want it.
It was working okay, then I started getting errors with IP's being duplicated, so I started over.
Here's what I have :
Orange France Livebox (dsl router)
ABS-g (dual ethernet)
ABS-n (pre-mixed g/n environment)
2 AExpress-g
Netgear Switch
Original setup :
livebox to netgear switch, feeding wired ABS-g (dual ethernet) and wired ABS-n (pre-mixed g/n environment). ABS-g acting as Main for WDS and feeding ABS-n via the switch, plus 2 AExpress-g via wifi.
It all worked for about 2 months. Then the problem with duplicate IP addresses.
So now the setup I have is :
Livebox wired to ABS-n, which then feeds to Netgear Switch to LAN wired, plus, 2 AExpress-g on WDS via wifi.
This works.
Here's the problem :
I want to extend the wifi network via wired, because there is some distance between the base stations. HOWEVER. Whenever I connect one of the base stations, which is configured as WDS Remote, via wired, I instantly loose my internet connection ... everywhere. Wired and wifi.
The base stations get self assigned addresses and I have to take the cable out of the ABS-Remote and then, take the cable (from the Livebox to the ABS-n) out of the ABS-n and put it directly into my Mac, to get the connection back.
I have restarted, zeroed everything many times. Finally I have narrowed the problem down to trying to have a wired connection to one of the WDS remotes. As soon as I plug a cable into a WDS Remote, I loose the connection.
Can anyone suggest what I might be doing wrong, or how I could reconfigure to enable either the ABS-g (dual ethernet) or one of the ABSExpress's to operate via a wired connection, thus much more effectively extending the wifi network.
Any help/pointers much appreciated.
Grant

Please take a look at this Apple Support reference to see if it will help you identify your AirPort: Identifying AirPort Hardware
I have seen that link elsewhere on this board. Unfortunately it's out of date. Yes you can go to the first page and visually identify your airport unit, but there is no model number next to the pictures. Clicking the 'More Info' link returns an error that the page does not exist.
The same holds true for the Apple pdf about designing Airport Networks. Dead link.
In a roaming network, ALL of the AirPorts must be connected by Ethernet or be on the same Ethernet subnet. Adding the Ethernet switch to one the 802.11n AirPort Extreme Base Station's (AEBSn) LAN ports will provide the additional wired ports for the AEBS and the AXs.
Since you have the AEBS connected by Ethernet to the Livebox, all of the AirPorts must all be reconfigured as bridges. Each will broadcast their own wireless network, but this network will have the same Network Name and use the same encryption setting. The only difference is that each AirPort must operate on a radio channel at least 3-5 channels away from that used by next nearest AirPort to prevent interference.
Having spent another hour or so, reconfiguring again, I've understood, that I cannot have an unwired ABS on a roaming network, even if it would appear to be on the same subnet. It gets no IP and is therefore lost in space.
So it would seem that anyone wishing to include some wired and some unwired ABS in a single 'seamless' network, needs to make a WDS for all the unwired ones ... and a Roaming network (with the same network name and password as the Main ABS network) for the wired ones.
This is what I have done and it looks to be working perfectly. All are in Bridge mode and all are on Automatic Channel ... and I note that the Airport Utility automatically gave a very distant channel to the wired ABS.
The network appears to be stable and fast. Phew.
As an aside ... it's a shame that the Airport Utility, whilst clearly a very clever piece of software, doesn't have more helpful explanations of what is going on. The wording is often ambiguous at best. A teeny bit more explanation would have saved me hours and hours of wasted time.

What is the difference between SWF and F4V in the context of Streaming or progressive Download?

Hello everybody,
I am absolutely a beginner in working with Captivate and furthermore my technological know how is not that good.
So, I have problems to understand if the export formats SWF and F4V are both capable to be published in the Internet as streaming video and as progressive Download? Well so, I do not really understand the difference between streaming and progessive download either?
Furthermore I was asking myself if this issue depends on how I imported flash videos (there are these two options) in my Captivate project during the production phase?
I would be very thankful for some helping information!
Greetings,
Mareike the beginner

Welcome to our community
I'm not certain I fully understand the differences myself, but will toss out what I believe to be true about the formats. Hopefully, if I'm incorrect in my bellief, someone with more definitive knowledge will chime in.
It was explained to me a couple of years back and is my understanding that "streaming" only applies to a video based format such as F4V, FLV and it doesn't apply to SWF. With SWF, you may specify a preload value. So when the SWF transmits from the web server to the PC, a certain percentage has to be received before play begins. But that's not streaming. It's preloading.
For streaming to occur, the web server establishes a communication channel between the server and the destination PC. This channel is monitored to see what speed is in use. Only enough information is then transmitted to be comfortable at that speed. If the speed improves during the connection, the server serves data at a faster rate. If the connection degrades, the information transmitted is also scaled back so as to accommodate the lower speed.
With SWF, after it has all been downloaded, a savvy user is able to poke around in their temporary internet files and save the SWF for play later. With streaming, this isn't possible because as the stream is viewed, it evaporates from memory.
Seriously hoping others will chime in here to confirm or deny this.
Cheers... Rick

Wired and Wifi has to be connected at the same time to not be disconnected!

I work as a tester for WoW and for the past few months, I’ve had connection issues. I’ve had Comcast come out a few times and they are so eager to leave they look up the speed and say, “Oh you are good on speed” well I’m not. Every few mins I’m disconnected from the server. It’s not my computer and I’ve done every thing WoW suggested. The ONLY way I’m able to stay online for an hour is I have to have the wired and WiFi connected at the same time on my desktop. If you have any suggestions let me know.

I have posted this many, many times here. See if this helps you understand how this process works with regard to system sounds and screen rotation lock.
System sounds can be muted and controlled two different ways. The screen lock rotation can be controlled in the same manner as well.
Settings>General>Use Side Switch to: Mute System sounds. If this option is selected, the switch on the side of the iPad above the volume rocker will mute system sounds.
If you choose Lock Screen Rotation, then the switch locks the screen. If the screen is locked, you will see a lock icon in the upper right corner next to the battery indicator gauge.
If you have the side switch set to lock screen rotation then the system sound control is in the control center if you are running iOS 7. Swipe up from the bottom of the screen to get to control center . Tap on the bell icon and system sounds will return.
If you are running iOS 5 or iOS 6, the system sound control is in the task bar at the bottom. Double tap the home button and swipe all the way to the right in the task bar to get to the speaker icon on the left side. Tap on that and the sounds will return.
If you have the side switch set to mute system sounds, then the screen lock can be accessed in the same manner as described above.
This support article from Apple explains how the side switch works.

Difference between SIP200 and SIP400

Hello.
Is there anyone who can explain what exactly BIG difference between SIP200 and SIP400 ?
They have same four bays, support almost same wan interface cards.
Please help me : )

Hi,
The difference is mainly speed:
The Cisco 7600 series router is an edge aggregation router, and the SIPs provide a cost-effective solution for customers seeking moderate- to high-port density and line rate services:
•The Cisco 7600 SIP-200 provides WAN edge aggregation through lower-speed and low-density SPAs for network environments requiring regional office connectivity to headquarters, or collapsed LAN/WAN deployment.
•The Cisco 7600 SIP-400 provides higher-speed, high-density link aggregation for network environments requiring leased line and metro aggregation.
•The Cisco 7600 SIP-600 provides a high-speed interface for WANs and metro aggregation.

Difference Between Aggregates and Compression

Hi,
Can you tell me what is the difference between Aggregates and Compression?
I know ,once compressed data is not available for deletion in request wise
and it moves from F table to E table .
Aggregates means ,data will move from cube to aggreagates(Baby cubes).
But my query is ,As both of them aggregates the data.which of them should be used. at what situation?
I hope you understood my Query.
Regards.
Naresh.

Hi,
An aggregate is a materialized, aggregated view of the data in an InfoCube. In an aggregate, the dataset of an InfoCube is saved redundantly and persistently in a consolidated form into the database.
Aggregates make it possible to access InfoCube data quickly in Reporting. Aggregates serve, in a similar way to database indexes, to improve performance.
especially in the following cases we create aggregates:
The execution and navigation of query data leads to delays with a group of queries.
You want to speed up the execution and navigation of a specific query.
You often use attributes in queries.
You want to speed up reporting with characteristic hierarchies by aggregating specific hierarchy levels.
For more info on aggregates go though the link below
https://help.sap.com/saphelp_sem320bw/helpdata/en/c5/40813b680c250fe10000000a114084/frameset.htm
Compression creates a new cube that has consolidated and summed duplicate information.
2. When you compress, BW does a group by on dimensions and a sum on measures... this eliminates redundent
information.
3. Compressed infocubes require less storage space and are faster for retrieval of information.
4. Once a cube is compressed, you cannot alter the information in it. This can be a big problem if there
is an error in some of the data that has been compressed.
For more info go though the below link

Why is my SSD showing 250mb/s difference between read and write...

So i have recently upgraded to a SSD in my 2011 MBP. 2.4Ghz i5 16Gb RAM. I swapped my HDD with a Samsung 840 Series 250Gb SSD, I noticed a huge speed bump. See attached photos. Read is clocked at 503MB/s peak, and Write is clocked at 260MB/s peak on the SSD. My Question is why is there a 250MB/s difference between read and write?? Using Black Magic Disk Speed test. Mac OS X 10.8.4 Beta.
Thanks

Writes are performed very differently on SSD than they do on a hard drive, and it is common for SSDs to have lower write speeds than reads.
It's actually quite interesting if you're a geek: http://en.wikipedia.org/wiki/Write_amplification
As long as the speeds do match your manufacturer specification for the model (and they do: http://www.samsung.com/us/computer/memory-storage/MZ-7TD250BW ) , there is nothing to be concerned about.

Difference between ACS and ISE

What is the big difference between the ACS and the ISE? We just purchased an ACS server to start locking down ports on our switches and use the Radius functions to better secure our wireless environment. It has been ordered but not yet arrived. I had a discussion with management today about preventing the IPads / IPhones / Smartphones / etc. of the world from accessing the network. If the user knows the credentials for getting their laptop onto the network then they can use these same credentials to get their IPad on the network. How do we detect and prevent is the current question.
In discussing with others the ISE comes up. The questions now become what is the big difference between this and the ACS. Do they work together or independently since they both seem to have "radius on steroids". Can I configure the ACS to do the same functions? I figure this will have to be something on a MAC address level anyway. Oh and one other thing. My wireless infrastructure is not Cisco.
Off to continue the research path ....
Brent

To put it simply I usually say ACS = RADIUS, ISE = NAC.
ISE will do RADIUS functions as well as NAC functions. Eventually you'll probably see ACS go away and be simply replaced by ISE.
ISE will do posturizing and profiling of a device to see if it truly meets requirements to be on a certain VLAN. For your example if you were to my credentials on my own smart device I would have access. ISE could profile this device to see if it truly is a corporate owned device or not. If it wasn't ISE can switch the network that the device connects to, say a guest network.
ISE can also do captive web portals for wired/wireless guest access.
I wouldn't rely on any type of MAC address authentication as I can easily spoof that.
