Hello everyone,

I have two HP Notebook computers (1 Vista  & 1 W7) connected wireless to my 2-month old DIR-655 (FW 2.03NA, HW vB1).   Both Notebooks have DHCP Reservations IP addresses assigned.  Both Notebooks have Sleep Mode enabled.

Almost every time the Vista PC “wakes-up from sleep”, it fails to be reissued its IP.  Sometime the W7 PC after sleep, fails to be reissued its IP.

When using DHCP without IP reservations, sometime, one or both computers fail to be issued an IP address, when returning from sleep mode.

The only way I’ve found to have the IPs reissued is to remove and reapply power to the DIR-655.

Anyone else have this issue or know how to fix it?

Thanks, JH

Are these wired or wireless to the router?

Are the drivers for the Laptops up to date?

[JoeHombre]

Thanks for the reply, Fuzzy.

Both are wireless to the router.  The W7 computer is 2 months old the VISTA one is about 4-5 years.  As far as I know both have up to date drivers (both are set for auto updates).

Prior getting the DIR-655 the router was a DI-624.  The VISTA computer worked well on the 624 but with the 655 from the start had the return from sleep IP issue - not every time after sleep but often.  The W7 computer has the same issue but not as often as the VISTA computer.

To me it seems like, after the sleep period, the 655 does not reestablished the computer’s IP address.

The DHCP Lease Time is set to 10080 minutes.

Do they do the same thing if Wire to the router?

Some things to try:
Ensure DNS IP addresses are being filled in under Setup/Internet/Manual? You can find these under Status/Device Info/Wan section.
Turn off ALL QoS (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices on the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall if you have this option.

What wireless modes are you using?
Try single mode G or mixed G and N?
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some devices don't support AES, im this case try TPIK only or Auto.
Any other WiFi routers in the area? Use InSSIDer to find out.
Turn off Short GI, WLAN Partiton and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.

Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Turn off all devices accept for one wired PC while testing.

Check cable between Modem and Router, swap out to be sure. I recommend CAT6 and the shorter the better if possible. I use a 1 footer. Swap cable between modem and router. Sometimes these in box cables are not made well.

Yikes, just noticed my typo of your name – sorry, Furry.

I’ll dig into all your comments to try and resolve my 655 issue.

Thanks, much for the info.

Keep us posted. Fuzzy is good to. Just dont call me shirley or late for dinner. Lol

Ladies and Gents,

When I first configured my new DIR-655, there were minimum changes made to the router’s settings until a solid working baseline was established.

Over about a two-week period, everything worked well so I then set-up the DHCP Reservations List for PCs and network devices; set Visibility Status (broadcast SSID) to Invisible; and enabled sleep mode for the wireless VISTA and W7 Notebook PCs.

A week or so later the issue of failure to re-connect the VISTA and W7 PCs to the DIR-655 after sleep (or Hibernation) – mode started.  I first thought that the DHCP Reservation feature wasn’t working because the PCs were not being assigned an IP address until the DIR-655 was powered OFF then ON.
I next turned-off the 655 DHCP Reservations and assigned each PC’s NIC a Static IP address but a few days later the sleep/hibernation-mode issue reappeared.

Later, I set wireless Visibility Status (broadcast SSID) to Visible.  With this change, it’s been two+ weeks now and the failure to reconnect after Sleep/Hibernation-Mode issue has not reoccurred.  So the issue may be related to this mode’s setting and/or the way the DIR-655 subsequently re-establishes the PC’s wireless connection.

Before I bring this issue up with D-Link Tech Support, I’d appreciate feedback from others that either confirm or disprove a connection between the DIR-655 Visibility setting and loss of PC wireless association after Sleep or Hibernate Mode.

All insight is appreciated.

Thank Ya, Joe

Hi Joe,

I have a D-Link DIR-655 A3 Hardware with Firmware 1.21 and have no problems connecting to my Dell Laptop when not broadcasting from the Router.

When you have connected to your Network, with your Laptop, go to Network and Sharing Center.

Look at Connections: Wireless Network Connection. Click on that you open up Wireless Network Connection Status. In that Window, click Wireless Properties.

Place a checkmark next to Connect even if the network is not broadcasting its name (SSID).

I am using Windows and not Dell's Software to connect to my Network.

Click OK Click Close and Close Network and Sharing Center.

That's it.

In Services, make sure that WLAN AutoConfig is set to Automatic.

You can stop broadcasting the SSID Signal Name, now.

JoeHombre,

I set up my 655 from day 1 to NOT broadcast its SSID.  I do not have DHCP reservations for any of my devices, though it's something I've been planning to do for a while now.

I do have an issue where my 655 will simply stop its wireless service altogether, sometimes in the middle of active web browsing.  A power cycle brings it back to normal.  I haven't had this happen in a long while, and thinking back I realize it's only ever happened when multiple wireless devices are connected to it.  Last occurance was with one W7 laptop in sleep mode, and another W7 laptop 'awake' and waiting/checking for any available software updates.  LAN devices have never lost service to the router.  Oh, and a scan for wireless networks shows that the wireless portion is no longer transmitting, though router status shows all should be fine.

So maybe it's somehow related to wireless connections, although it shouldn't matter.  If you feel like experimenting, maybe you can power off one of the laptops for several days and see if the active one still loses its connection to the router (using your 'troubled' setup, of course).

Good luck and please keep us posted.

bgarcia17, thanks for your comments.

In addition to the two PCs, I have two DIR-624s set as APs which are included in the “List Of Networks” that the PCs can connect to.  Plus I have a DAP-1522 Bridged to the DIR-655.  So there is a lot of wireless activity going-on here.

Your issue with losing wireless is interesting.  When my issue first appeared, like you, I’d resolve it with a power-cycle of the 655.  Later, I found out that changing the PC’s Wireless adapter from automatic IP and DNS to static IPs addresses also reestablishes the wireless connection (do this under wireless network properties and make sure you assign the addresses within your network’s IP range).  It was this discovery that led me to link the possibility of losing and not being able to regain an IP as being my issue.

When the problem I’m having occurred, I have not checked to see if wireless was still ON but I suspect it was because my PCs are not both coming out of Sleep Mode at the same time and the unaffected PC still has internet access while the one “waking-up” doesn’t.  When your issue occurred, were both of your PCs without a connection on just the one?  Also, were other wireless devices still working?

Your comments are very helpful.

The first time it happened, all wireless devices lost service.  Had two laptops going at once, and both lost the wireless connection to the router.  Scanning for networks didn't show "other network", that's how my network shows up since I'm not broadcasting the SSID.  When the router stops broadcasting, all wireless devices lose their connection to the router, thus losing complete network connectivity.

Actually, I now realize that this has happened 3 times.  The first time, it happened overnight and the only wireless activity was from Apple iPads or phones.  I blamed it on a friend trying to hack my network, since I woke up to find the wireless signal nonexistent.  This was the only time my laptop failed to connect coming out of sleep, but obviously it was because the router had stopped its wireless service.  The other two times have been with only two wireless devices connected, but one time I'm pretty sure one the laptops was actually sleeping.  Both time, I was actively on the internet, and suddenly the wireless connection disappears completely.

Don't have a clue what's going on, but it's so rare for me that I live with it.  Most of the time it's just me anyway, and it hasn't failed me when I'm alone.  I still monitor this forum to see if someone with more frequent and predicable failures has found a solution I can use.

You do have a lot of wireless activity around you, and it's been suspected of maybe being the cause.  I can't say that applies to me, cuz I live on an acre and neighbors' networks are very weak.  I still don't see a router completely shutting off its wireless radio because of congestion, but I don't design these things.

Any status on this? Find a solution?

[JoeHombre]

Since my earlier posts, we moved from IL (Charter ISP) to CO (Comcast ISP) so got very busy with the move.  Didn’t have much trouble-shooting time but the problem (computers not getting IP address from time to time) still persisted in CO as well.

When I looked at the DNS assignments, they were still set to Charter but the computers would acquire IP addresses then after a while they would not be reissued, so needed to do a  DIR-655 power-cycled to issue the IP addresses.

After a few weeks, I set the DIR-655’s DNS addresses to Comcast ones and TA-DA, no more IP issues – both computers now stay connected.

For those having IP reassignment problems, I suggest that you check your ISP’s DNS IPs and verify that they match your router’s settings.

My bad for not updating this post.

Furry, thanks for the kick in the butt jump-start.

Glad you go it working well.
Enjoy.
