Title: Terrible wireless connection
Post by: Buc_Nasty on October 13, 2011, 01:23:37 PM
I have a DIR-655...it disconnects every minute. Just to read these forums then register I got "this page cannot be displayed" messages several times, and have to press refresh all the time to get pages to load.

The laptop will indicate full bars for connection strength, then all of a sudden go to 1 bar, then just disconnect. The network will not even appear in available networks, then it will reappear and connect again. Browsing is essentially impossible.

I have the latest firmware installed on the router

on laptop over wireless, Speedtest was .92mbps download, 25ms ping, .12mbps upload
on desktop hardwired speedtest was 25.48mbps download 25ms ping, 3.36 upload

Hardwired there are no problems whatsoever. I've reset the router, but dont even know where to start after that and don't have the skills or time to spend hours and days tinkering with my router.

Even while accessing the router setup page or whatever its called (192.168.0.1) i got several "this page cannot be displayed" messages.

The laptop I'm on connects to other networks just fine, and other laptops have the same problem on this network/router. Comcast cable and cable modem

WPA2, I'll provide any other info thats needed

HELP PLEASE!!!

What HW version is your router?
What FW version is currently loaded?

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
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.

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.
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.
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP.

What wireless modes are you using?
Try single mode G or mixed G and N?
What security mode are you using? WEP, WPA or WPA2? Preferred is WPA-Personal. WPA2/Auto TPIK and AES.
What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area?

Thank you very much for the response.

What HW version is your router?     A4
What FW version is currently loaded?   1.34NA,  2010/04/16

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router? Stand alone modem from comcast - Arris TM722
What ISP Modem make and model do you have? ^
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.

Ensure DNS IP addresses are being filled in under Setup/Internet/Manual? You can find these under Status/Device Info/Wan section. if you mean under "dynamic IP (dhcp) internet connection type" the primary and secondary dns servers both show 0.0.0.0. Connection type is set to dynamic IP
Turn off ALL QoS (DIR only) GameFuel (DGL only and if ON.) options. I unchecked "enable QoS engine"...that what you meant to do?
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual. was already off
Turn on DNS Relay under Setup/Networking. was already on
Setup DHCP reserved IP addresses for all devices on the router. can you explain what this means/how to do it? sorry
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP. done. were set for port and address restricted

What wireless modes are you using? it was set for mixed n and g. I tried switching to just n...that a good idea? cant have it on TKIP and AES while in only N mode tho so i set it for AES - let me know if i should go back to mixed and TKIP and AES
Try single mode G or mixed G and N? ^
What security mode are you using? WEP, WPA or WPA2? Preferred is WPA-Personal. WPA2/Auto TPIK and AES.
What wireless devices do you have connected? 3 iphones, as many as 5 laptops at a time but usually only 2 or 3 at once. Sometimes 2 desktops hardwired but then it would be 2 less laptops wireless. Usually only 3 max devices connected but in the evenings more...evenings is when the connection is awful but a router should be able to handle this many people connected to it no? and at ALL times the hardwired internet is super fast

Any cordless house phones? Live in a 4 story apartment building with 24 people in it, in range of several other same sized ones (boston MA). we don't have house phones and none of the apartment buildings come with them so I doubt there are many around but there could be. Definitely not in my building though
Any other WiFi routers in the area? LOTS of other wifi routers in the area


I changed the wireless channel to 10 instead of 6...i read that they all come default on 6 so everyone's on it? maybe this will help? I'll see after a day or two of trying it

1.35NA Firmware (ftp://ftp.dlink.com/Gateway/dir655/Firmware/dir655_FW_135NA.zip)

Dowload INSSIDER (http://www.metageek.net/get_inssider_today/) and see what channels have less use on them.
Title: Re: Terrible wireless connection
Post by: Buc_Nasty on October 19, 2011, 07:07:35 AM
hm i pressed check for updates through the router and it said up to date but I just put 1.35 on.

Should I apply all the changes listed above again?

If all devices work with wireless N, is it better to use mixed mode or just N?

Also in regards to inssider and the best channel - should i choose the "best channel" option or select a certain channel to stay at? Is there a feature in inssider that will tell me the best one to use over time? there are a lot of networks around 3, 6, and 11, and its hard to tell/i dont know a different one to choose that would be better...

also should i add dhcp reservations for each device i want connected? what is the benefit of doing this?

thanks

before updating lets see if we can get you going on what you have loaded now.

Yes if ALL of your devices support N mode at 2.4Ghz then yes, change to single mode N only and run. You can leave the Cipher type settings to Auto TPIK and AES. Some of your device might not support AES so you might need to check on this if you go AES only.

Changing channels is good. I might try channel 1 if you see 3, 6 and 11 being used. Maybe try 8 or 9.

I recommend using reservations for ALL devices connected to the router as this provides the same IP address per devices that will not change, wont break any options you might set up for a device if the address happens to change, thus breaking the option, and helps in trouble shooting.

I already upgraded to 1.35...for the moment its working much better, we'll see if it stays this way.

Wheew, you got some interference going on there. Wow. Ok man, good luck. One thing about doing FW updates for next time. Do the following:
Factory reset the router.
Update the FW.
Factory reset once more.
Configure the router.


Keep us posted. Enjoy.
Title: Re: Terrible wireless connection
Post by: Buc_Nasty on October 19, 2011, 08:04:50 AM
should i factory reset then re-update firmware then factory reset now or just leave it?

looking at graph what would you suggest - choose best option or pick a channel and if so which channel?
(see what I mean haha)

thanks for all the help and quick responses
Title: Re: Terrible wireless connection
Post by: FurryNutz on October 19, 2011, 08:21:43 AM
I would re do the FW to be sure. This probably wont cure your interference issues however will make sure the FW is well seated in the router.

Wow, I might try 1-3 or 8-9 and see what goes on. This is kind of a crowded area.  :-\
Title: Re: Terrible wireless connection
Post by: Buc_Nasty on October 19, 2011, 02:32:40 PM
So I'm still having the same problems although not quite as bad as when i made my first post.
I made most of the changes listed above once i upgraded firmware but not all...

Anyways, pretty often (at least once every 20 minutes) the wireless disconnects, my network disappears from the list of available networks. Then it reappears and reconnects usually within a minute...what could be causing this?
Title: Re: Terrible wireless connection
Post by: FurryNutz on October 19, 2011, 02:45:23 PM
I would presume that the near by WiFi routers are at the root of your issues here.
Have you tried turning off SHORT GI and WMM Enable under Advanced/Wireless?

One other thing you can try is to lower the out put power of the wireless from High to Medium and see if this might help. There so much radio going on that signals are causing some interference. Lets see if you can make your broadcast foot print smaller to say just your room or with in 10 feet and see if you still see disconnects.

Keep us posted.
Title: Re: Terrible wireless connection
Post by: Buc_Nasty on October 19, 2011, 09:48:00 PM
Just to be sure, I'm going to re-install the firmware the right way, and do everything on the first list and the output power thing.

The problem with that is I'm splitting cable between my apartment and the one below so it can't be too weak, but anywhere in either apartment right now is full bars so i hope its not a problem.

This forum is great btw you guys are really helpful i appreciate it.
Title: Re: Terrible wireless connection
Post by: FurryNutz on October 20, 2011, 07:13:05 AM
What? splitting cable? Do you mean TV cable splitters? Eh, those are not recommended and if you have to, use only one and use a GOOD one. They can lower the signal the more you have on the line.
Just so you know, when doing FW updates, don't do it over wireless. Wired only.
Title: Re: Terrible wireless connection
Post by: Buc_Nasty on October 20, 2011, 10:04:10 AM
Its split from the street going to a cable box then the other side is split again going to another cable box and the modem...
Title: Re: Terrible wireless connection
Post by: FurryNutz on October 20, 2011, 11:27:07 AM
Hmm...well I would have the ISP check to make sure that this (split) is done right and the signal levels are where they should be at the modem. They can check that. You can also check the modem logs too. See if there is any odd disconnects.
Title: Re: Terrible wireless connection
Post by: davevt31 on October 20, 2011, 12:01:42 PM
Any cable setups that I have used or setup for others have always had the cable modem on the first split of the incoming cable.  You will get signal loss going through multiple splitters.
Title: Re: Terrible wireless connection
Post by: Buc_Nasty on October 24, 2011, 06:14:21 PM
One splitter is -3.5 db and one is -4.0....could this be causing anything?
Title: Re: Terrible wireless connection
Post by: FurryNutz on October 25, 2011, 07:21:02 AM
The more splitters you have on the light the more the signal is attenuated thus the ISP modem wont get a good signal and any thing after that the quality of signal and data can be effected. Its preferred to use no splitters or have a dedicated cable line for Internet. If you must have a splitter(s) use good quality or if needed, possible use of good quality cable line amplifier for long distance runs however thats worst case scenario.
Title: Re: Terrible wireless connection
Post by: Buc_Nasty on October 26, 2011, 06:56:04 PM
I rearranged it so it comes from the street thru one splitter and one end goes to modem while the other is split again to the 2 cable boxes. ZERO improvement.

I'll note again, the hardwired connection is always super ultra fast not even one bit of lag, while wireless really struggles all day and night, not just peak hours.
Title: Re: Terrible wireless connection
Post by: FurryNutz on October 27, 2011, 07:03:48 AM
I would recommend you have a review at the 855 forum and review this:
http://forums.dlink.com/index.php?topic=41071.0 (http://forums.dlink.com/index.php?topic=41071.0)

Really looks like your area is highly congested with WiFi.
Title: Re: Terrible wireless connection
Post by: Buc_Nasty on October 27, 2011, 02:47:35 PM
Yea my problems sound very similar to what everyone else was describing.

A few questions:

1) The fact that I will still show full 5 bar wireless signal but not be able to load pages is a symptom of too many nearby networks right? The majority of times I have connection/webpage loading issues I will have full signal the whole time just nothing will load...it wont even say limited connectivity or anything just full strength connection but no loading pages.

2) In terms of messing with the power levels, correct me if I'm wrong, but I'm assuming that lowering the power level will lower the area my wireless reaches, but you're hoping that will cause it to not overlap/interfere with other signals? In that case, for example in my room I usually get around 5 bars all the time, but lowering the power will average 3, but the fact that there isnt so much overlap will make it so i actually have a better connection with 3 bars than 5? BTW every 10 minutes or so it will drop to 2 or 3 bars for a minute, then go back to 5 (did it while i was typing this).

3.) I would assume not, but would a wireless amplifer device help me to somehow overpower the other networks? (shooting in the dark on this idea)

4.) I could combine wireless with people in the apartment above me, which would actually be great because it would save everyone a lot of money, but we'd have 7 wireless smartphones, 7 wireless laptops, and 2 hardwired desktops all connected (as opposed to 5 smarthpones and 4 wireless laptops, 2 desktops now...would this extra use cause more problems than its worth?

5.) a couple of the networks of the 27 shown on inSSIDer will have amplitudes around 5 times the height on the graph as any others...which i assume makes them faster? How come those get so high and mine does not?

Thanks again for the assistance

If your router is set up and you connecting to your SSID, yes you should beable to load pages however, if there is some sort of interference, which you seem to be experiencing with all the other routers near by, then yes as well that this can impact the loading of pages and data comming from the router via WiFi. We presume that wired doesn't experience this?

2) In terms of messing with the power levels, correct me if I'm wrong, but I'm assuming that lowering the power level will lower the area my wireless reaches, but you're hoping that will cause it to not overlap/interfere with other signals? In that case, for example in my room I usually get around 5 bars all the time, but lowering the power will average 3, but the fact that there isnt so much overlap will make it so i actually have a better connection with 3 bars than 5? BTW every 10 minutes or so it will drop to 2 or 3 bars for a minute, then go back to 5 (did it while i was typing this). Yes, hoping to make your wifi foot print smaller as to not over lap the other routers foot print and keep yours from over lapping if possible.

3.) I would assume not, but would a wireless amplifer device help me to somehow overpower the other networks? (shooting in the dark on this idea) Yes, in some cases, over powering could help your signal interference however remember that your signal will go farther and also now you might become someone else's interference on there system.  ::)

4.) I could combine wireless with people in the apartment above me, which would actually be great because it would save everyone a lot of money, but we'd have 7 wireless smartphones, 7 wireless laptops, and 2 hardwired desktops all connected (as opposed to 5 smarthpones and 4 wireless laptops, 2 desktops now...would this extra use cause more problems than its worth? Yes and is encouraged if you and others are all on the same ISP and willing to share the radio waves and any monitary obligations you should agree too. Yes, if you can all be on the same SSID and then change the channels between each router, then this would help maintain Wifi connections better. Just be aware that bandwidth could be an issue if someone is gaming and someone else is streaming video and such.   ::)

Maybe I'll try an amplifier haha too bad for other people.

One other thing that happens is when i try to even go into the router setup, it will say "could not connect to the router, the network appears to be down" thats still just the same problem right its definitely the fact that there are too many wireless networks around?
