Amazon E4200 - Works fine... When it works

Date: June 13,2012
Rating: 1
Have had this router for several months now. I have 75Mbps internet service incoming from ISP. ISP cable modem feeds this router directly. From the router I feed a 16 Port Gigabit unmanaged switch which feeds several Ethernet jacks throughout my house including 2 powerline network devices. This router also feeds a VOIP adapter for our phones as well as a handful of wireless devices (iPhones, iPads, laptops, etc.)
This router does the job when it works. I run a business and sometimes have to download several Gb of updates and upgrades depending what I'm currently working on. We also have Netflix and use it frequently. I find several times a week, this router simply drops our internet connection. It is totally random and happens whether or not any other computer is accessing internet. I bought this router because of the higher speeds it can deliver wirelessly. This router was recommended by several sales associates over D-Link's offerings.
Here's what happens. I'll be surfing along on my wired connection and all of a sudden I just get page not available faults. My phones all stop working of course and any media streaming we are doing from internet is halted. Network wise, everything keeps chugging along just fine. I can still stream from my home server no problem. When this happens I have to go into the router status and "release IP address" from ISP and "renew IP Address". This is as I said totally random. Sometimes I can go a few weeks without incident then I can have it lose connection several times in the same week. I RMA'd my first e4200 as Cisco had no idea. My replacement does exactly the same thing. The unit I have is the V1 and I have the most recent firmware which I thought was supposed to help with this problem. I've heard the N900 (which is the V2 of this router is much better but now I'm gunshy to spend another couple hundred).
This router also has very poor range on both bands especially the 5GHz band. It is physically located in the basement office and the second floor of the house can't get reasonable signal on the 5Ghz band. Almost as soon as I walk out the front door I lose all signal as well.
I can really NOT recommend this product at all.

Try to check the router's firmware if it is updated. As for the wireless configuration, try to use 2.4GHz and select standard 20MHz channel 9 with wpa2-personal as the security key.

I can record voice memos fine using the built-in iPhone 4 mic. And my Bluetooth headset (Jawbone Era) works fine when I leave messages on voice mail systems etc. when calling on the iPhone 4. However, I cannot record voice memos with my Bluetooth mic.

I can record voice memos fine using the built-in iPhone 4 mic. And my Bluetooth headset (Jawbone Era) works fine when I leave messages on voice mail systems etc. when calling on the iPhone 4, so it appears my headset mic is fine. I can also use voice activated dialing, although it fails miserably interpreting numbers. However, I cannot record voice memos with my Bluetooth mic. I just get barely audible static. Any suggestions? Thanks.

Hello, did you ever get an answer to your question? I just picked up a Jawbone Era and using on an iPhone 4s running 5.0.1. Seems to work fine on regular calls, but not on the built in Voice memos application. It worked fine on my older Jawbone Icon, but haven't tested on the 4s or iOS 5.
Thanks!

I've been working with AI for some time time now & would love to have a light weight viewer to open the files. The bridge is fine when we're working but just being able to toggle through folders is impossible otherwse

I was thinking of keeping things a bit easier in the way of clicking & dragging artwork into Illustrator. The bridge is fine when we're in the print shop & working but still has problems with some of the file extensions with the vectors. A lightweight no frills viewer that would open anything that Illustrator would open, so we could just burn through our regular file folders without opening AI or the bridge would be a great deal. Add the PS extensions too & we could dance by the firelight. Just offer it to those with the software & the valid codes for their software. I mean if there would be a problem with folks just grabbing it up. Love to have it though.

A thumbnail preview file icon option would be nice. CorelDRAW has had this capability for its past few versions. It does make it a whole lot easier conducting searches in Windows File Explorer. You can find the right files pretty quickly and then drag/drop them into CorelDRAW.

The iTune Remote App has stopped finding my iTunes library when connected to wifi from my main router, but works fine when connected via second wifi router on the same network (different SSID)

I'm running iTunes Remote App from a couple of iPhone 5's and a first generation iPod Touch. iTunes is running on a PC - Windows 7. My home network runs two Wifi Routers, each with a different SSID. I've had no problems with the Remote app running this set up for the last 8 months but recently the App can only find my iTunes library when the iPhone/iPod is connected via one specific router, when connected to the network via the other router, no iTunes library is found. I'm also running an Apple TV and it's the same as the iTunes Library, only visible via the one SSID.
Everything else seems to work fine when connected via either router, eg Internet on the iPhones (definitely via wifi)
I've tried renewing the lease on the iPhone wifi connection, restarting everything.....several times.....
It used to work fine, this only seems to have been a problem in recent weeks
Any help or advice would be much appreciated
Thanks

It turned out to be the firewall settings on our router. Her machine was sending traffic that our router interpreted as a DoS attack and blacklisted her Airport's MAC address. That's why it would work fine if she switched to Ethernet.

I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device

I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device (iPhone) using debug build. When running with a release build, the result handler is never called (nor is the fault handler called). Viewing the BlazeDS logs in debug mode, the call is received and send back with data. I've narrowed it down to what seems to be a data size issue.
I have targeted one specific data call that returns in the String value a string length of 44kb, which fails in the release build (result or fault handler never called), but the result handler is called as expected in debug build. When I do not populate the String value (in server side Java code) on the object (just set it empty string), the result handler is then called, and the object is returned (release build).
The custom object being returned in the call is a very a simple object, with getters/setters for simple types boolean, int, String, and one org.23c.dom.Document type. This same object type is used on other other RemoteObject calls (different data) and works fine (release and debug builds). I originally was returning as a Document, but, just to make sure this wasn't the problem, changed the value to be returned to a String, just to rule out XML/Dom issues in serialization.
I don't understand 1) why the release build vs. debug build behavior is different for a RemoteObject call, 2) why the calls work in debug build when sending over a somewhat large (but, not unreasonable) amount of data in a String object, but not in release build.
I have't tried to find out exactly where the failure point in size is, but, not sure that's even relevant, since 44kb isn't an unreasonable size to expect.
By turning on the Debug mode in BlazeDS, I can see the object and it's attributes being serialized and everything looks good there. The calls are received and processed appropriately in BlazeDS for both debug and release build testing.
Anyone have an idea on other things to try to debug/resolve this?
Platform testing is BlazeDS 4, Flashbuilder 4.7, Websphere 8 server, iPhone (iOS 7.1.2). Tried using multiple Flex SDK's 4.12 to the latest 4.13, with no change in behavior.
Thanks!

After a week's worth of debugging, I found the issue.
The Java type returned from the call was defined as ArrayList. Changing it to List resolved the problem.
I'm not sure why ArrayList isn't a valid return type, I've been looking at the Adobe docs, and still can't see why this isn't valid. And, why it works in Debug mode and not in Release build is even stranger. Maybe someone can shed some light on the logic here to me.

List View filtered by multiple params (one from cookie) - works fine when groups are expanded initially, but hides filtered items when collapsed and then expanded.

Hello!
I have a page with a list view web part. I am applying multiple filter parameters to it: I have to display documents for all US locations (general) and also filtered view of documents for user's office location. I am setting the user location Cookie and
i have configured webpart with Param to read it. Second filter value is hard-coded (Non-specific location). It all works FINE when i set the list View to expand all groups by default. The problem starts when I set it to be collapsed from the start:
Collapsed group shows correct number of items to be inside but when i expand it, the 1 extra LOCAL item filtered by {PARAM} is missing from inside this expanded group. Only items filtered by a "hardcoded text param" are being shown. And
again - when i change the view and set it to be expanded by default - ALL items are being shown without any problem! Only thing that breaks it - setting of collapsed-expanded for this view groups. nothing else.
Any suggestion on how to work with this thing?
I can't make all groups expanded by default - too many documents, but it only time when it works.
I tried changing view design, other characteristics, but nothing makes it change the behavior so far.
I really want o avoid creating custom "hardcoded" views for each location where location is predefined instead of dynamically read it from cookie. For me it looks like something is connected with PARAM as only these items are affected by this weird
behavior. Thank you in advance!

Hi Olga
I have tried the method you have mentioned, but the jquery function is not working to collapse the groups.
I have tried 2 approaches, but none of them is working fully:
1) Raising the Click event as follows
for (var i = 0; i < links.length; i++)
if (links[i].href == "javascript:" && links[i].onclick.toString().indexOf("ExpCollGroup")
> -1)
links[i].click();
2) ExpCollGroup()
Please suggest or send the correct method to collapse

Ipod nano 5th gen - works fine when plugged in either to wall or computer and appears to be fully charged but as soon as it is unplugged screen goes blank and will not start - is the battery shot?

Yes, your battery is likely toast and in need of replacement. Not much else for troubleshooting here. Sorry.

After using my iPod classic in my infinity G35 a few weeks ago, I took it out of the car and it no longer works. Just a white screen with the web address for Apple iPod support. Worked fine when hooked up to iPod jack in car. But wont work anywhere now

After using my iPod classic in my infinity G35 a for the last few weeks, I took it out of the car and it no longer works. Just a white screen with the web address for Apple iPod support. Worked fine when hooked up to iPod jack in car. But won't work anywhere now. I tried re-setting but has not worked. Any ideas would be appreciated.

I finally resolved my problem after spending way too much time on it. I simply handed my 160GB iPod to my husband to put his fav Stones & Beatles songs on and I went back to my 80GB Microsoft Zune which has never disappointed me.
After spending so much time trying to figure this out I did finally take it back to Apple Store who performed a diagnostic and found there was a problem with the device. They replaced it with a refurbished one which has similar issues. All I wanted to do was listen to my music. Was that too much to ask? So I am happy to be free of this problematic device. No more Apple for me!!

Ever since i downloaded OSX Mountain Lion, Express VPN no longer works properly for me. Even though it says I am connected, webpages refuse to load. However, everything works fine when its turned off. I cannot go on many websites without the VPN.

Ever since i downloaded OSX Mountain Lion, Express VPN no longer works properly for me. Even though it says I am connected, webpages refuse to load. However, connection speed is fine when its turned off. I cannot go on many websites without the VPN. My current location is Shanghai, China. OSX Mountain was installed this morning and everything worked fine until then. Is Express VPN not supported? What do i need to do in order to get it working again on my Macbook Pro (early 2011). I want to be able to go on websites such as Youtube, Facebook, Twitter, ect...

Hi,
I am having the same issue listed above on my new Mac Mini i just bought, I also contacted Express VPN support and got the same instructions with exception of the command to run in the utilities terminal. I tried the steps listed, and both commands (posted here, and sent to me directly by Express VPN support), and still unable to connect on my Mac Mini running OS X 10.8.2, but I am able to connect on my iPad and my MacBook which is running Mac OS X 10.6.8. Usually Express VPN is spot on with their customer support, but this is taking longer to get resolved. Here is the steps sent to me
Try doing the following to see if the problem gets resolved:
Please follow the instructions here: https://www.expressvpn.org/support/setting_dns_servers_mac_os
(should still be the same for Lion) and then add the following DNS servers: 8.8.8.8 & 208.67.222.220. After adding the DNS servers, please do the following steps as well:
Note: If you're connecting to your ISP via a PPPoE connection, then set the DNS servers on the PPPoE connection itself and then restart your computer for the DNS settings to take effect.
1. Click on Applications
2. Click on Utilities
3. Click on Terminal
4. Type the following command (without the quotes): "sudo killall -HUP mDNSResponder"
5. Press enter and then try reconnecting to the VPN.
If you're still unable to connect, please send us in the latest log files.
Hope this helps. Let us know how it goes.

My "Apple TV" is hooked up via HDMI to my Marantz receiver. Everything works fine when watching movies. When trying to watch a show or listen to music, there is no sound. Has this happened to anyone else?

Perhaps you should ask over in the iPad community, you may get better answers there.
It's actually my fault that psoon ended up here ... s/he intially posted over at Home Sharing, and I tried a relocate request to Apple TV rather than iPad.

Have you tried the standard fixes:
- Reset:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Restore the iPod from backup via iTunes
- Restore the iPod to factory defaults/new iPod.
If still problem you likely have a hardware problem and an appointment at the Genus Bar of an Apple store is in order.

Macbook works fine when plugged in, turns off when unplugged.

Hello all,
As stated my 2008 Unibody 13 inch, serial number W8******1AX turns on and works fine when it is connected to power.
When it is unplugged it instantly turns off and turns its fans on full until it depletes the battery (so it is obviously getting power.. just not where I want it)
Since the problem began I have tried two new batteries, neither of which had any different symptoms.
Before this, the computer had an intermittent life, it would turn off when it saw fit, which got progressively worse.
I have followed the guides to resetting the SMC but have had no luck
I have been running it without the battery (to save it charging and discharging for no reason) and sometimes when plugged in without a battery
the magsafe green indicator light goes from dim to bright.
With the battery installed it stays bright orange until it is charged and then switches to bright green.
(I have tried it with another charger, same symptoms)

There may be a hardware cause behind the symptoms you cite, so a diagnostic
is recommended to see which parts are weak or failed in the computer. A visit to
an Apple Store with Genius bar may be helpful, as they can perform testing there.
A call ahead or use their web page, to schedule an appointment, is advised.
In the US and Canada, the Genius bar at a retail Apple Store can perform
a diagnostic service, for no fee, even on Apple products without AppleCare.
See links:

Genius Bar - Apple Retail Store:

List of Apple Stores, cities, countries:

Also authorized Apple service providers who can test, repair and guarantee their
work should be able to handle an out-of-warranty older Mac, within age limits...
Ones too old for the Apple Store could be serviced at a Specialist, instead.

Apple Portables: Calibrating your computer's battery for best performance
•The power adapter can be problematic and cause issues, so there's this:

Also another item, other than keeping the magnetic connections clean of
debris, grime, and corrosion, is to check the MagSafe Board or have it
checked as part of a greater diagnostic. This board is behind the port
that supplies the computer and the battery with power from the adapter.
When it partially fails or if/when one of the connecting wires or plug fails
you can find odd issues or partial use. The battery may charge but it
may not be able to power the computer, and other odd effects.
https://www.ifixit.com/Device/MacBook
In older portable Macs, this was generally called a 'DC-in board' and as
such, you could read about it in an iFixit repair guide for the MacBook
model you have. These vary so the matching article is recommended to
see if that is something you may want to try. But I would have diagnostic
testing done and avoid additional damages from attempted DIY efforts.
There have been a few reports of other failure on the logic board that
contributes to a partial failure of the charging system, so about all this
may do is troubleshoot around the failure without finding an exact cause.
However it goes...
Good luck & happy computing!
