Title: Dropped Coverage
Post by: dachadster13 on November 17, 2009, 01:19:59 PM
Hey guys. I just setup a friends wireless system and I am having some issues with the wireless. The wireless printer stays attached all of the time but when he hooks his laptop, or any laptop for that matter, it will connect for a few minutes, then drop, then reconnect automatically.  Here are the steps taken on my end:

-Update firmware to 1.32 (I'm pretty sure that's the newest from D-Link)
-Tried different channels in case other wireless were working on that same one
-Changed types of allowed connections, N + G + B, N + G, and so on.

I am stumped and would like to get this taken care of. If anyone can offer some assistance it would be greatly appreciated.  Thanks in advance.

What happens when you don't attach the wireless printer? Is everything ok?

I found it useful to read the help and the FAQ about cipher types when I was setting up my G/N clients, at some point I was getting behaviour like you describe, so getting the correct combination should fix you up too.  Unfortunately I can't tell you what specifically I had to set.
There's an FAQ on the support site about getting 300mbps connections and I found some good info in there too if I recall correctly.

good luck

Interesting suggestion about disconneting the printer. I will try that this weekend.  As for the cipher type, I thought the only thing you could do with that is set the encryption..TKIP or AES, or am I thinking of something different? Thanks for the responses.

It is, I think the settings are TKIP AES or both, and adjusting that, WPA/2 and b/g/n mode made all the difference for me.
YMMV

I set wireless for auto WPA and WPA2 then set cypher for TKIP and AES.

Some network things I have can not do AES only.

Have you all made sure to set the Channel Width to Auto 20/40 Mhz?
This will allow N and G client at the same time.

Figure out the common type of encryption all your adapters support.
Then set to fixed cipher types instead of Auto selections.

Also, this router is REALLY sensitive to positioning! I have got drastically different results depending on where I place it, even from items in the next room. Something as simple as a piece of furniture in the way can change things. I now have it on the wall at about 4 feet with the aerials pointing in slightly different directions.

There are some advanced options also (especially the 801b network guard) that you can fiddle with, but I would warrant that yours is most likely due to environment..... unless.... it's the old deathentication problem, in which case I wish you luck.

I would advise taking a close look at the wireless drivers on the laptop. If you wanted more feedback/help it would be good if you could let us know what the wireless adapter chipset is on the laptop and whether or not you have windows managing it, or the producing manufacturer manager (i.e. a dlink wireless manager on the laptop), or the chipset manufacturer wireless manager. For example, I have an DLINK usb N adapter on my main machine but I use Ralink driver to manage wireless much more sucessfully, I have an intel chipset wireless on one of my laptops and intels "zero config" wireless utility is notoriously hopeless at keeping connections, so I get far better results using the Win7 OS wireless manager, etc.

Post some more details and let us know how you get on :)

None of his devices are running B, just G, so does the above even apply to me? He is also out of town for a week so I'm not going to be able to get over there and poke around. As for the actual dropped connections, the laptop, which is running XP with the Intel wireless chipset, is sitting no more than 5 feet from the router when we tested it.

Also with drivers, I know XP doesn't natively support WPA without a stand alone hotfix, or SP3. I don't think that is the problem seeing how I am able to connect for a period of time but will check.  Thanks again for all the suggestions. Will post again after I try them out.

Xp does support WPA.
