Title: Spotty 5GHz connection.
Post by: Hunter X on January 20, 2014, 09:21:55 AM
I've had the DGL-5500 since October and it's been nothing but trouble for me. At first it was constant dropped connections on both the 2.4GHz and 5GHz bands (But my own troubleshooting lead to the discovery of bad LAN/WAN ports. Router reporting cable was "disconnected" when it was connected). Got it replaced via D-Link RMA and have been using the replacement with minor issues since (5GHz was always a problem though). I simply stopped using the 5GHz band and relied on only the 2.4GHz band, but apparently I was missing out on approximately 50% of the speed I would normally get. Speedtests on the 2.4GHz band gives me a down speed of 1Mbps and up of 1Mbps tops. When the 5GHz band works, I get up to 15Mbps down and 10Mbps up. Now, my issue with the 5GHz band is the constant connection drop. When I'm connected, everything would be going along just fine and my connection would go from "Internet access" to "No internet access" in Windows and of course, not browse the internet. The connection doesnt get dropped as in the connection disappears, but rather I would remain connected without internet access. The only "fix" is manually disconnecting from the network and reconnecting to the same connection (which then works again). I've ruled out the issue with my computer since it happens with my HTC One also. I have a WHR-HP-G54 with DD-WRT as a client bridge connected to the DGL-5500. I previously used a Verizon Actiontec MI424WR router and had no issues at all with that setup.

I am located in NY, so the router is in its intended region. For every FW update, i've performed the factory resets as suggested and set up everything from scratch. I'll probably get called out for this, but it's not "my" internet per se, but I do pay my share for it. I have family members who live 3 houses down and they share their internet with me and in return I pay a portion of the bill as well. The ISP is Verizon FiOS. They also use a Verizon Actiontec MI424WR router. They pay for 50/25 service, but I only use 15/10 (configured Streamboost for 15/10). I turned off any settings on the DGL-5500 related to DNS (DNS relay, etc.) Every other setting is as suggested (unicasting, multicasting, etc.). 2.4GHz is set to mixed g/n as I have a 3DS which doesn't support wireless-n and have the channel set to 11 (least populated channel in my area). I use WPA2 personal with AES encryption.
The bridge I'm using is a Buffalo WHR-HP-G54 with dd-wrt firmware loaded on it. Since the originating wireless signal comes from 3 houses down, the bridge is configured with an aftermarket yagi antenna. I have only 1 device that supports wireless-ac on 5GHz, my HTC One. Since I rely on the bridge, I can't exactly test without the bridge (unless someone knows how I can tether my phone to the router). I know I'll probably get turned away due to my setup, but thanks in advance for any help.

Post by: FurryNutz on January 20, 2014, 10:51:07 AM
I see, this sheds more light on the subject.

What freq does the bridge run on? 2.4 or 5Ghz? What mode is it running on? Never mind, I see it's a 2.4Ghz G bridge. I don't think this could be effecting your 5Ghz radio however anything is possible. I see more problems possibly on the 2.4Ghz if the bridge is in the same freq though. How close is the bridge to the 5500 and I presume the bridge is on a different channel from what the 5500 2.4Ghz radio is using?


A test you can try with the HTC is set a single mode N with Auto band width. Does the HTC support AC modes? If it does, switch to single mode AC and test again. You might see what bandwidth the HTC support on AC and N mode. It's possible the HTC might not support 80Mhz. Try a lower setting.

How far is the HTC from the 5500?
Any other WiFi neighbors on 5Ghz near you?
Title: Re: Spotty 5GHz connection.
Post by: Hunter X on January 20, 2014, 11:05:03 AM
The bridge is running on channel 6 wireless-g (family's router is chanel 6 wireless-g with WPA2 AES). The DGL-5500 is on channel 11 to avoid interference. The bridge is 6 feet away from the DGL-5500. The only setting I can change for WiFi on my HTC One is which band to use. According to a spec sheet, the HTC One supports 80MHz. My phone is about 40-50 feet away from the router. As far as I'm aware, almost no one else is using the 5GHz band (I see only 3 signals in my area, but on different channels apart from mine, so no interference)

What kind of building material is between the HTC and the router when 40-50feet away? 5Ghz is best in line of sight with nothing in between accept maybe one wooden wall or wooden structure.

Well, I may have to agree with the OP on the spotty 5.0.

I just got the Microsoft Wedge mouse for my tablet which has Bluetooth.  It is interfering with the 2.4 ghz connection, so I went to the 5.0 ghz (I had both 2.4 and 5.0 set up but never used 5.0 for anything).  It connected for about 30 seconds, then it drops.  I tried just 20 mhz, 20/40, just n, n and ac.  DNS relay turned on and off.  I can't connect with a Dell tablet or an Alienware m11x.

Just to make sure I am able to use the 5.0 on the devices, I connected a DIR-825 with the dd-wrt software and I am able to keep a 5.0 connection AND on the 2.4 ghz, there is no interference with bluetooth.

Both routers are set up the same WPA2-personal with AES for security, they just have different SSID's.  The 825 had 20/40 set and just n for both 5.0 and 2.4

This post is not to say that this may be entirely the routers fault as there may be setting on the computer that I have not changed.  I am open to try other settings but resetting the whole router will be something I don't want to do right now.  Also assume that I have done the common remedies, ie restart, updated drivers etc, etc.

I haven't had an issue on the 5Ghz radio yet.

Any other 5ghz radio sources near by?
How far away is the client devices from the router?

I can get to my 5Ghz radio from the living room which is about 20feet away from my router back in the office down the hall way. Signal could be a bit better I think. I use Mixed mode on the 5Ghz and Auto 20/40/80Mhz. WPA2/AES only.
I'll have to check the channel, I believe that last time I used it it was on 36. I had a buddy of mine change his to 149 last nite on his 5500.

No other sources of 5.0. INSSIDer sees the short activity then the drop and it will eventually not even get tracked anymore, while the router is still on and 2.4 is working.

Within 20 feet, next room.  I have auto scan and it picks one of the lower channels.

When I did the firmware update to 1.11 initially, I had done a full reset.  I did the beta update too, if that makes any difference.

Info I got from D-Link:
"If the connection is dropping after a few seconds -- then a couple of things to check:  Wi-Fi password entered not matching, mismatching encryption settings, beyond the range of coverage --probably not the case for the user, or might be a incompatibility issue.

The DGL-5500 has been tested with Broadcom based, Intel based, and Realtek based adapters - so I do not think that this is the issue.

The DGL-5500 has been tested by the Wi-Fi Alliance in their test bed for compatibility with other adapters from different vendors."

Are there any other devices online while you are testing speeds?
Do you get the same speeds when testing wired?
Do you have access to a different AC supporting device to test for a comparison?
Are there any other devices online the main host site and router during this speed test since you have a bridge between the 5500 and the ISP modem/router?

The AC speeds is showing hear what your getting since you said you set the SB for 15/10 right? 2.4Ghz seems low...

Post by: Hunter X on January 21, 2014, 02:06:39 PM
Correct, I'm getting the speeds I set on the 5GHz band, but on 2.4GHz, I'm losing speed. As far as I'm aware, there shouldn't be any devices connected to the main host besides my bridge. I'll test by connecting directly to the bridge and then connecting to the dgl-5500 directly via ethernet. I did the test 5 feet away from the router.
Title: Re: Spotty 5GHz connection.
Post by: FurryNutz on January 21, 2014, 02:11:09 PM
Ok, See if you can test a different 2.4Ghz device if possible with the 5500s WiFi...if that does the same thing then possible there could be some interferences on the 2.4Ghz radio...

I might also try to get the 5500 farther away from the bridge, as far as possible. Even though channels are different, could still be some noise by the bridge being that close.

Then see if you can move the 5500 farther away from the bridge...far as possible...might incur getting a long LAN cable.  ::)

Seems like the 5Ghz is working better now or well, however 2.4Ghz is now the focal point?  ???

5GHz will work fine until it just loses connectivity randomly (while still remaining connected) whereas 2.4GHz is rock solid with slow speeds.

That's an odd one.  Are you able to ping the router IP when the connection drops? And have you tried setting up full static IP settings outside of the dhcp range.  Could be a dhcp renewal issue? I'm not sure how to do any of those on a Mac I'm a windows user.

Post by: B.Banner on January 22, 2014, 08:57:26 PM
Not sure on the logging. There's debug settings and saving to a syslog server but I've never messed with it.

The next time the connection dies open up command prompt.  Depending on what OS there's multiple ways to get there.  Easiest is Windows key + R -> CMD.

In the command prompt type;
ping 192.168.0.1

See if it times out or can reach the 5500.

So I have experienced bad gaming on XBL while using a DIR-868L bridged to the 5500 as the main host router on the 5Ghz radio. 15 ft one room away, gaming lag was fairly significant. I removed the 5500 and install a DIR-865L and the lag went away.

I've forwarded my experienced and included this thread to D-Link for review. I'll post back when I hear something.

I wanted to expand on this. It was determined that the DIR-868L in bridge mode while connected to the DGL-5500 on 5Ghz seemed to be the issue and D-Link is aware if it. I'm waiting on fix information for the DIR-868L bridge mode issue. I connected the DIR-865L in bridge mode to the DGL-5500 and I did not experience any issues with that bridge.

Still having issues. I've tried all my routers as bridges, a Buffalo WHR-HP-G54, ASUS RT-N65U, and a Fonera router and all exhibit bad 5GHz connections. I'm pretty sure it might be a bad radio chip in my DGL-5500, but D-Link wants me to talk to one of their senior engineers about it and am told I'd get a call at a certain time, but never actually get the call. All inquiries about getting it replaced are ignored. This would be the second time i'm RMAing this router; The original one I had had dead WAN/LAN ports from the get-go, the replacement, the one i'm trying to RMA has bad 5GHz connectivity (can't transfer a 100mb zip from my computer to my Raspberry Pi without losing connection) and would constantly lock up requiring a reboot. I've done everything from factory resets, downgrading, upgrading, etc. nothing works. :(

*pulling hair* They don't want to do an RMA because my router is getting a private IP address (because I'm running a wireless bridge, which I clearly explained). I really don't see what that has to do with anything. I give up on this router, it's probably best I trash it. My issue is dropped connectivity to the router, not the router losing connection to the internet and constant lockups...
