Best practice of Wireless settings E4200

I Have a Linksys E4200 router and would like to know what the best practice is for the Wireless settings?
My settings are currently:
This is good or should I change something, for example difference Network name for both or channel ?
Please somebody help/advise me.

Optimal settings. And also be sure to give the network's 2 different names. Example. HomeNetwork and HomeNetwork5G 2.4GHz Mixed: If you have mixed devices. If not. G or N. Channel Width: 20MHz Channel: 1,6 or 11. 5GHz N only. Channel Width: 40MHz Channel: Does not matter on the 5GHz band.

Best practice architecture Wireless security

What is the best practice architecture for wireless to the wire network?
Use AP to Firewall and it to a router using RADIUS?

Is any place in Cisco that I can use to see Architecture recomendations that integrete Wireless, Radio (Microwave) and Voice over IP com-plete system?

using one of the 802.1x types (i.e. LEAP, EAP-FAST, PEAP) with WPAv2 (AES encryption). Too bad that there are not many wireless adapters support AES.
All Cisco wireless product support AES in 12.3(2)JA recently.
Also, you may want to configure WDS for radio management.

What is the best Practice JCO Connection Settings for DC Project

When multiple users are using the system data is missing from Web Dynpro Screens. This seems to be due to running out of connections to pull data.
I have a WebDynpro Project based on component development using DC's. I have one main DC which uses other DC's as Lookup Windows. All DC's have their Own Apps. Also inside the main DC screen, the data is populated from multiple function modules.
There are about 7 lookup DC Apps accessed by the user
I have created JCO destinations with following settigns
Max Pool Size 20
Max Number of Connections 200
Before I moved to DC project it was regular Web Dynpro Project with one Application and all lookup windows were inside the same Project. I never had the issue with the same settings.
Now may be becuase of DC usage and increase in applications I am running out of connections.
Has any one faced the problem. Can anyone suggest the best practice of how to size JCO connections.
It does not make any sense that just with 15-20 concurrent users I am seeing this issue.
All lookup components are destroyed after its use and is created manually as needed. What else can I do to manage connections
Any advise is greatly appreciated.
Thanks

Best practices for permission settings in SharePoint 2010

Hello,
Does anyone know if there is a good "best practices" paper\article for SharePoint permissions in SharePoint 2010. I have a pretty good idea of what i would like to do. The problem is that there is another group that handles security for the SharePoint
sites. It's really bad. Individuals have permissions and some of the group memberships really don't make much sense.
I am tasked with cleaning up our permission settings in our farm but I would like something to give to that team. I want it to show what it is we need to do and why. What the best practices are. It's also going to be good for me as I will use it
to compare with what I would like to see done.
Can anyone recommend a link that covers this in detail.
Thanks

Best Practice Bandwidth & Video Settings

Does Adobe have a best practice for bandwidth and video settings for meeting rooms? Please share .
Many thanks...
Lynn

OK. For live I find it depends on the number of individuals streaming live video. If you are in the 1-5 range, there shouldn't be a big issue for using the highest quality setting for the live video. 5+ I would start bringing it down in quality and ultimately you may need to take it to the lowest quality for a large number of live videos.
For on-demand video, I stick with settings around the following:
FLV
720 X 480
800 kbps
These numbers are just a guide, going above them may lead to performance issues, and going below may improve the experience. In the end it all comes down to what you are willing to trade in quality for bandwidth required to deliver it.
For room bandwidth settings, I generally don't change it from LAN unless I know that my audience will require some bandwidth throttling. Shifting down to DSL/Cable will reduce the quality of everything in the room by limiting how much bandwidth can be used. It's a good feature if you need it, but can be frustrating if you don't.
These are just my thoughts on settings as a user, as I don't work for Adobe. I've not seen any documentation from Adobe about recomendations (just a chart of what bandwidth will be consumed on average by each function in Connect). If anyone else has thoughts or guidelines they have put together, please share them.

Best practice for Wireless ap vlan

Is there a best practice for grouping lightweight access points in one vlan or allowing them to be spread across several ??

Whether you have multiple sites or not, it's good practice to put your APs in a separate and dedicated VLAN.
If your sites are routed sites, then you can re-use the same VLAN numbers but make sure they are on separate subnets and/or VRF instance.

Best practices in wireless configuration?

Hi,
Is there a best practice document that shows 3500 AP with 5508 controllers? The questions I have are below.
1. Do I configure each AP to non overlapping neighbor channels(1,6,11 for 2.4GHz) or leave that to controller to decide? Does controller change the channel of an AP when it sees congestion on a specific frequency?
2. For 5 GHz is it good idea to bond the channels? What frequency to use for neighboring APs? OR again, leave it to controller to shift as needed?
3. For security what's best practices? 802.1x or different?
Thanks,
Sm

1. Do I configure each AP to non overlapping neighbor channels(1,6,11 for 2.4GHz) or leave that to controller to decide?
Let the controller(s) decide. By default the Dynamic Channel Assignment (DCA) verifies the channel for interferrence every 600 seconds. Because you have 3500 then make sure you enable Event Driven RRM (Radio Resource Management) on both channels.
Does controller change the channel of an AP when it sees congestion on a specific frequency?
The controllers will not change the channel when it sees congestion. The controller will change the channel if it sees interference on the same channel. The CleanAir will change the channel when it sees interference from non-AP interference like Bluetooth, Microwave ovens, cordless phones, etc.
2. For 5 GHz is it good idea to bond the channels?
Sure.
What frequency to use for neighboring APs? OR again, leave it to controller to shift as needed?
Leave this option in default.
3. For security what's best practices? 802.1x or different?Sure.

RAW Best Practices

I've used my D7000 and Apple Aperture for over a year now. In the past, I've always shot JPEGs exclusively, but as I've read more about the virtues and flexibility of RAW, I've been considering the change. I know you can shoot RAW+JPEG, but I'd like to avoid that practice.
Since the camera is not applying it's picture control touches to RAW files, what are some best practices for batch settings on import?
Is there anything special I should be doing on RAW import? Are presets suggested beyond the default "RAW Fine Tuning" settings? My RAW photos are somewhat flat and lact saturation, which I understand is a result of them being unprocessed by the camera picture control settings.
Or, if I do decide to standardize on RAW, will I have to then manually touch up every shot?
Thanks in advance, John

I do think that I will backtrack and use the RAW+JPEG option and keep the pair of files.
Good idea IMO.
...the Nikon software in fact rendered the JPEG and RAW identically
...the "Nikon way" (ie - JPEG) vs. the RAW. Whether I like the Nikon processing or not on a particular image, at least then I can decide and have the RAW file to manipulate.
The above part is perhaps mis-stated.
DSLRs capture light data on a sensor. Each different camera internally processes that data extensively using proprietary algorithims to save the vendor's version (for that specific camera) as a "RAW" file (e.g. what Nikon calls NEF). The resultant NEF file saved in-camera must be converted to be viewed. Conversion is an irreversible one-time process.
Apple converts RAW files,
Adobe converts RAW files,
Nikon converts RAW files,
etc.
Each vendor's conversion will be different. The camera vendor has a head start on best doing the conversion because only the manufacturer fully knows how the original data was processed in-camera.
After conversion each vendor saves the data in a standardized lossless format like TIFF or PSD.
Or the vendor can discard much of the image data, compress and save the file in a standardized lossy format like JPEG.
Each vendor's conversion will be different.
So the camera processes the image once: light data--->RAW file (NEF). Then someone (Apple, Adobe, Nikon, etc.) converts the RAW to a viewable image. You can choose whose conversion you prefer but you cannot modify the original Nikon/Canon/etc. processing.
Note that a Nikon JPEG is by definition very not the same as a Nikon RAW file (NEF). They may have similar "feel" because a Nikon raw conversion was done in both cases, but the JPEG file:
• has had a very large amount of image data discarded by the JPEG algorithim
• has been permanently modified by various in-camera settings.

Swtich with 2 wireless routers (configuration for best practice/advice?)

HI folks,
I have a gigabit switch, and 2 wireless G routers. I'll leave the model numbers out as it's fairly irrelevant - all linksys.
Router 1 is used as a router only (due to location in basement)
Router 2 is used for wireless only
My current network setup:
DSL MODEM (accessed on 192.168.2.1 - can not be changed) > Router 1(192.168.1.1)
Router 1 > Switch (i believe it can't be changed 192.168.2.12 - no webgui)
Switch > everything else including Router 2
Everything works except Router 2 - can't connect to it wired or wirelessly until connected directly to a pc.
Is my setup wrong
and/or is there a best practice?
Many thanks!!!

What is the model number of the switch?
Normally a switch that cannot be changed does not have an IP address. So if your switch has an address (you said it was 192.168.2.12) I would assume that it can be changed and that it must support either a gui or have some way to set or reset the switch.
Since Router1 is using the 192.168.1.x subnet , then the switch would need to have a 192.168.1.x address (assuming that it even has an IP address), otherwise Router1 will not be able to access the switch.
I would suggest that initially, you setup your two routers without the switch, and make sure they are working properly, then add the switch. Normally you should not need to change any settings in your routers when you add the switch.
To setup your two routers, see my post at this URL:

Best Practice for FlexConnect Wireless roaming in MediaNet environment?

Hello!
Current Cisco best practice recommendations for enterprise MediaNet design, specify that VLANs be local to a switch / switch stack (i.e., to limit the scope of spanning-tree).
In the wireless world, this causes problems if you want users while roaming to keep real-time applications up and running. Every time they connect to a new AP on a different VLAN, then they will need to get a new IP address, which interrupts real-time apps.
So...best practice for LAN users causes real problems for wireless users.
I thought I'd post here in case there's a best practice for implementing wireless roaming in a routed environment that we might have missed so far!
We have a failover pair of FlexConnect 7510s, btw, configured for local switching for Internal users, and central switching with an anchor controller on the DMZ for Guest users.
Thanks,
Deb

Thanks for your replies, Stephen and JSnyder.
The situation here is that the original design engineer is no longer here, and the original design was not MediaNet-friendly, in that it had a very few /20 subnets bridged over entire large sites.
These several large sites (with a few hundred wireless users per site), are connected to an HQ location (where the 7510s in failover mode are installed) via 1G ethernet hand-offs (MPLS at the WAN provider). The 7510s are new, and are replacing older contollers at the HQ location.
The internal employee wireless users use resources both local to their site, as well as centralized resources. There are at least as many Guest wireless users per site as there are internal employee users, and the service to them consists of Internet traffic only. (When moved to the 7510s, their traffic will continue to be centrally switched and carried to an anchor controller in the DMZ.)
(1) So, going local mode seems impractical due to the sheer number of users whose traffic bound for their local site would be traversing the WAN twice. Too much bandwidth would be used. So, that implies the need to use Flex / HREAP mode instead.
(2) However, re-designing each site's IP environment for MediaNet would suggest to go routed to the closet. However, this breaks seamless roaming for users....
So, this conundrum is why I thought I'd post here, and see if there was some other cool / nifty solution I wasn't yet aware of.
The only other (possibly friendly to both needs) solution I'd thought of was to GRE tunnel a subnet from each closet to the collapsed Core / Disti switch at each site. Unfortunately, GRE tunnels are not supported in the rev of IOS on the present equipment, and so it isn't possible to try this idea.
Another "blue sky" idea I had (not for this customer, but possibly elsewhere in the future), is to use LAN switches such as 3850s that have WLC functionality built-in. I haven't yet worked with the WLC s/w available on those, but I was thinking it looks like they could be put into a mobility group, and L3 user roaming between them might then work. Do you happen to know if this might be a workable solution to the overall big-picture problem?
Thanks again for taking the time and trouble to reply!

Best practice for frequently needed config settings?

I have a command-line tool I wrote to keep track of (primarily) everything I eat and drink in the course of the day. Obviously, therefore, I run this program many times every day.
The program reads a keyfile and parses the options defined therein. It strikes me that this may be awfully inefficient to open the file every time, read it, parse options, etc., before even doing anything with command-line input. My computer is pretty powerful so it's not actually a problem, per se, but I do always want to become a better programmer, so I'm wondering whether there's a "better" way to do this, for example some way of keeping settings available without having to read them every single time. A daemon, maybe? I suspect that simply defining a whole bunch of environment variables would not be a best practice.
The program is written in Perl, but I have no objection to porting it to something else; Perl just happens to be very easy to use for handling a lot of text, as the program relies heavily on regexes. I don't think the actual code of the thing is important to my question, but if you're curious, it's at my github. (Keep in mind I'm strictly an amateur, so there are probably some pretty silly things in my code.)
Thanks for any input and ideas.

There are some ways around this, but it really depends on the type of data.
Options I can think of are the following:
1) read a file at every startup as you are already doing. This is extremely common - look around at the tools you have installed, many of them have an rc file. You can always strive to make this reading more efficient, but under most circumstances reading a file at startup is perfectly legitimate.
2) run in the background or as a daemon which you also note.
3) similar to #1, save the data in a file, but instead of parsing it each time save it instead as a binary. If you're data can all be stored in some nice data structure in the code, in most languages you can just write the block of memory occuppied by that data structure to a file, then on startup you just transfer the contents of the file to a block of allocated memory. This is quiet do-able - but for a vast majority of situations this would be a bad approach (IMHO). The data have to be structured in such a way they will occupy one continuous memory block, and depending on the size of the data block this in itself may be impractical or impossible. Also, you'd need a good amount of error checking or you'd simply have to "trust" that nothing could ever go wrong in your binary file.
So, all in all, I'd say go with #1, but spend time tuning your file read/write proceedures to be efficient. Sometimes a lexer (gnu flex) is good for this, but often times it is also overkill and a well written series of if(strncmp(...)) statements will be better*.
Bear in mind though, this is from another amateur. I c ode for fun - and some of my code has found use - but it is far from my day job.
edit: *note - that is a C example, and flex library is easily used in C. I'd be surprised if there are not perl bindings for flex, but I very rarely use perl. As an after thought, I'd be surprised if flex is even all that useful in perl, given perl's built-in regex abilites. After-after-thought, I would not be surprised if perl itself were built on some version of flex.
edit2: also, I doubt environment variables would be a good way to go. That seems to require more system calls and more overhead than just reading from a config file. Environment variables are a handy way for several programs to be able to access/change the same setting - but for a single program they don't make much sense to me.

Current best practice for Time service settings for Hyper-V 2012 R2 Host and guest OS's

I am trying to find out what the current best practice is for Time service settings in a Hyper-V 2012 environment. I find conflicting information. Can anyone point me in the right direction. I have found some different sources (links below) but again the
are not consistent. Thanks
http://blogs.msdn.com/b/virtual_pc_guy/archive/2010/11/19/time-synchronization-in-hyper-v.aspx
http://technet.microsoft.com/en-us/library/virtual_active_directory_domain_controller_virtualization_hyperv(v=ws.10).aspx
http://social.technet.microsoft.com/wiki/contents/articles/12709.time-services-for-a-domain-controller-on-hyper-v.aspx

From the first link provided by Brian, it does state that the time service should be off, but then the update changes that statement. Still best to rely on the first link in the OP - it was written by the guy that has been responsible for much of what
gets coded into Hyper-V, starting from before there ever was a Hyper-V. I'd say that's a pretty reliable source.
Time service
For virtual machines that are configured as domain controllers, it is recommended that you disable time synchronization between the host system and guest operating system acting as a domain controller. This enables your guest domain controller to synchronize
time from the domain hierarchy.
To disable the Hyper-V time synchronization provider, shut down the VM and clear the Time synchronization check box under Integration Services.
Note
This guidance has been recently updated to reflect the current recommendation to synchronize time for the guest domain controller from only the domain hierarchy, rather than the previous recommendation to partially disable time synchronization between the
host system and guest domain controller.

Wireless roaming best practice

When setting up standalone access points on the same SSID is it best to use multiple channels that do not overlap (ie 1,6 and 11) or use the same channel for every access point?
We have 1 SSID in our office spread over 3 access points and currently I have it set to use channels 1, 6 and 11 on each. Is this correct or should I use the same channel on each?
Devices seem to operate and roam correctly I was just querying the best practice.
We cannot justify the cost of WDS.

Hi Scott,
Thanks buddy! Much appreciated. We are extremely cautious when it comes to changing "working" deployments. The move to new versions of code (for both Voice and Wireless) is always well researched to the point of being almost paranoid ;-)
The "better safe than sorry" mantra, is a great rule of thumb when working with these products. Too many bugs for my liking.
Cheers!

Best practice - Heartbeat discovery and Clear Install Flag settings (SCCM client) - SCCM 2012 SP1 CU5

Dear All,
Is there any best practice to avoid having around 50 Clients, where the Client version number shows in the right side, but client doesn't show as installed, see attached screenshot.
SCCM version is 2012 SP1 CU5 (5.00.7804.1600), Server, Admin console have been upgraded, clients is being pushed to SP1 CU5.
Following settings is set:
Heartbeat Discovery every 2nd day
Clear Install Flag maintenance task is enabled - Client Rediscovery period is set to 21 days
Client Installation settings
Software Update-based client installation is not enabled
Automatic site-wide client push installation is enabled.
Any advise is appreciated

Hi,
I saw a similar case with yours. They clients were stuck in provisioning mode.
"we finally figured out that the clients were stuck in provisioning mode causing them to stop reporting. There are two registry entries we changed under [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CCM\CcmExec]:
ProvisioningMode=false
SystemTaskExcludes=*blank*
When the clients were affected, ProvisioningMode was set to true and SystemTaskExcludes had several entries listed. After correcting those through a GPO and restarting the SMSAgentHost service the clients started reporting again."

Document FPS Settings? Best Practice?

hi all,
just made a simple "move ball along to accelerometer". i've set the fps to 30, activated gpu rendering,
exported it to my phone for testing and... hell... this runs pretty slow! "ball" is a simple one colored 40x40 px sprite.
except some (4) debug textfields there is anything else on the stage.
is this a fps setting issue? any best practice values? i could not find anything in the docs the mentions the fps
settings so i'm not even sure they are important for the compiled app... are they?
thanks

So, I've been playing around with this, and here's my initial findings.
Pushing the frame rate up to 60 made things choppier, but I'm just using the Adobe example code and I think that can be optimized.
I have it set to 18 FPS, and it's not bad. Not great, but not bad.
I changed out the drawn image to use a png file that's 30x30.
I put an image below the png file so that there is a background.
I turned off debugging.
While not perfect, I think this would be acceptable performance for a game with just these few objects. Next up, I'm going to try adding more objects and see how far I can push things.
P.S., the example code I'm using can be found here:
http://help.adobe.com/en_US/FlashPlatform/beta/reference/actionscript/3/flash/sensors/Acce lerometer.html
Works in Flash CS5.
