I tried to search for this solution but I had no luck with the forum search results.
I would say 3 times a day, my router blocks WIRELESS access to Google and all Google associated properties. There are no issues from wired base computers. The wireless block is only temporary and it usually comes back within 3 minutes.
Why is this happening?
-
This seems odd...something in any filtering you have configured for WiFi devices?
What Wireless devices do you have?
Has a factory reset been performed?
Internet Service Provider and Modem Configurations
- What ISP Service do you have? Cable or DSL?
- What ISP Modem Mfr. and model # do you have?
- Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values (http://forums.dlink.com/index.php?topic=53008.0)
Router and Wired Configurations
- Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
- Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
- Turn On/Off DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench (http://forums.dlink.com/index.php?topic=53222.0)
- Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting.
- Ensure devices are set to auto obtain an IP address.

Thanks for getting back. A little background. I recently moved from Ontario to Saskatchewan. The issue persisted in both locations even though I was on different ISPs and modem manufacturers.
My current ISP is Sasktel and I believe it is DSL service
My modem is actiontec v1000h
Good advice, I'll check on the MTU with the ISP and I'll report back if that makes a difference
The devices I have in my household are 3 iPads, 3 iPhones, 1 remote control
I also am using a WAP from Dlink DAP-1525
I'll try those other suggestions. Thanks.

- If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT (http://www.practicallynetworked.com/networking/fixing_double_nat.htm) and How NAT Works (http://cognitiveanomalies.com/cisco-nat-how-nat-works/). To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.

Seems like odd behavior for sure if only WiFi devices are being block with only Google. I'd turn OFF the DAP and directly connect to the 857 first and test to figure things out. Once you get it going, then turn on the DAP.
What mode is the DAP running in? AP?

I'll look into it more. The problem is that in my other house (3 months ago) the router connected with modem without a router and had the same issue. I'll give it a shot though.
Also, coincidentally I was sent a link today on my iphone and it couldn't connect to the site. So it would appear as if the problem is not exclusive to Google. I'll let you know what happens.
What I'm not understanding is why I can't access the website for about 5 minutes and the suddenly, the issue corrects itself. Could this be a defective router?
-
Ya seems like there might be a DNS issue here...Keep us posted...
-
Since the issue of certain sites not being available only affected wireless devices. I fooled around with a couple of settings. It appears as if the Auto Channel Selection was the issue. I've disabled it and set the channel to 44.
I have a DIR-857 in my home and a DAP-1525 that I'm using as an access point. My question is, should both devices be on the same channel? Currently, I have one device set to channel 44 and the other to 40.
Thanks for the help. Much appreciated.
-
They need to be on different channels. Farthest appart as possible. 36 and the other on 149 if you can.
-
With regards to the 2.4 ghz band, I've left that on auto channel, should I change this?
-
Yes, Set one for chl 1 and the other to 11.
-
The access point does not broadcast in 2.4 Ghz band. In that circumstance, should I still set the router to one of those two channels or does it matter?
Thanks for the support; very helpful.
-
Pick a chl thats not being used by any other neighboring routers.
-
I thought I had this thing figured out. I'm still having issues unfortunately.
When I reserve devices on my home network for a certain IP, are some of them still supposed to appear in the list of Dynamic DHCP clients?
Also, when I look at the wireless status of some of my devices, the router shows me IP addresses that look like 0.0.0.0 Is this normal? Sometimes the 0.0.0.0 will change to a 192.168.0.114 as I'm looking at the status panel.
I tried every one of your suggestions that you listed above. I'm still not having any luck. Again, no issues with wired devices. The issues come from my wired connections.
-
They should appear in the Dynamic List with a Reserved status or Never maybe...
Hmm..I might do this, hassle however, factory reset. Power off EVERYTHING accept for one wired PC. Get it reserved. Save settings and power on the next device. Keep doing this until you get them all reserved. Reboots might need to be done each time to ensure the settings are saved well.
I'd set up the SSID and leave the security open for now while your doing this. Once you get it all reserved. Test the wireless devices to ensure they are getting internet to correct sites. Test each device out. If you can get to this and it working. Turn on WPA2/AES only or Try Mixed TPIK and AES.
Let us know...
Maybe someone can review your router settings with you using Link> teamviewer (http://www.teamviewer.com) if your interested. Its safe and secure.
-
"They should appear in the Dynamic List with a Reserved status or Never maybe..." You lost me on this sentence. Should the items appear in the Dynamic List or not?
For now, it appears as if everything is working out OK. If things don't, I definitely would like someone to review my settings.
Thanks a lot.
-
They should appear in the list, There will be a least date and time expire. I believe for Devices that do not have a IP reservation. For ones that do have a reservation, "Never" I think should display instead of Date and Time.
I'd be interested in know if you experience any WiFi or heat issues with your unit. I made a mod to mine as a tinker to see what happens. I did this to my 827 as well regarding the metal heat sink mod. I know some people expressed concerns about this so I posted some info to help out with this.
Hope its working better for you. Keep us posted.
Enjoy.
-
I think it would be best if someone could review my settings with this teamviewer. Can you do it or someone with your expertise?
-
Send me a PM. Ill connect after lunch.
-
OK, done. Thanks.
-
I connected however you were not at your PC sir. ::) Let me know when a good time for you is and we'll try again ok? ;)
-
I'll be here from now until 5:00PM CST
-
We found a mis-configured DAP-1525 connected thats the culprit here. ::)
Devices connected to the 857 are all now working...
Let us know if you can get the DAP re-configured.
-
I'll leave the AccessPoint turned off for two days to confirm that this is the issue. As far as I can tell, the access point is configured correctly. Are you aware of any resources online that might be able to help me configure this AccessPoint correctly?
I used the Dlink sync technology between router and access point to configure the access point; I assumed that would be enough.
Thanks a lot for helping me yesterday.
-
IF the AP is wired to the back of the 857, then just log into the 1525 and run thru the set up wizard or you could manually set it up..it has similar Wifi UI as the 857 and should be under Setup/Wireless/Manual. You can use the same SSID name and PWs just make sure the channel is different. You'll need to keep the AP wired to the back of the 857 for this mode.
Might be of some help:

You're indicating to do this wizard, it would make more sense to have the router linked directly to the access point? Currently as you know, I'm using a switch. I don't see the difference actually. Let me know, thanks in advance
-
Ya if you reset the 1525, and wired to either switch or router, you should be able to log into the 1525 at 192.168.0.50...The run thru the wizard...or manually set it up. If you can get to the AP and can't figure it out, let me now and I'll get on TV.
-
I think I'm going to go without the access point in my new home. It doesn't seem like I need it. For whatever reason, the router is giving me a much farther range than it did before we made the adjustments to the 5 GHz band. Do you know why this would happen?
-
We changed from Mixed all modes to a single mode operation. In some cases this helps the single as the radio doesn't have to do multiple modes any more, just one so the signal is improved.
Also be aware that the 857 has better WiFi connections speed than the 1525, the 857 supports up to 450Mb connections on 5Ghz, were the 1525 only supports 300Mb.
Keep the 1525 on hand for now. You could it it as a bridge later on.
-
It turns out that I do need that access point. Are there any settings that I can post here that might determine if it's conflicting with my router? I did the setup process over again from the beginning. I also lowered the transmission signal strength of the access point.
Thanks a million for all the help
-
Should try the following:
IP address: 192.168.0.50
Subnet Mask: 255.255.255.0
Gateway:192.168.0.1
Can be same SSID name and PW as 857, just make sure channel is different. Keep farthest way.
Use same WiFi modes as the 857.
-
Okay, the only thing that I didn't do was the gateway setting. I'll see how this works out. Thanks

-
Thanks for everything bro. I got the access point working without issue. I'm able to access all websites without issue. RESOLVED

Good to hear, Enjoy.
