The Graveyard - Products No Longer Supported => Routers / COVR => DIR-635 => Topic started by: SAINT1976 on November 14, 2011, 04:53:21 AM

I run a DIR-635 behind a ISP provided modem, along with a Toshiba Satellite laptop and a network attached storage device. The overall Internet connection seems alright but the NAS access speeds are very inconsistent, especially when transferring files to/from the NAS unit, and sometimes file transfers are even interupted followed by error messages stating that the NAS unit (or file) is unavailable.
I can sometimes also tell from the Network connection indicator in the Windows toolbar (I use Win 7) that the connection speed goes up and down.
The problem is that I don’t have enough knowledge in this field to figure out which part of my network that’s causing this problem, ie. whether it’s the modem, the router, the NAS unit or if it’s some sort of setting that I’ve overlooked.
Any input to help me identify this problem and also to help me optimise the speed is highly appreciated.
Thanks in advance.

It's probably due to the router having some impact on the network as it's trying to handle traffice from the Internet and network on the LAN side. It's preferred to connect a external switch to the router, then connect all of your wired devices to the network switch. This will eliminate any router interference between PC and NAS however still get Internet just fine. Let us know what you think.

Thanks for your reply FurryNutz.
Any specific specs i should look for in a switch?
Cheers!

What region of the world are you in?
D-Link DGS
HP JD869A#ABA V1405-5G <I prefer HP ::)
NETGEAR GS
These are all Gb switches and backwards compatible. I recommend upgrading to Gb on everything on the LAN side and use Cat 6 cabling. It's cheap and works great.
Let us know what you do.

I live in Sweden.
I'll check out on these products asap and will keep you notified.
Once again, many thanks for your help.

Hi again!
I added a D-Link 5-Port Switch DGS-1005D 10/100/1000 (Gigabit) to my setup this week and a cat6 cable between the switch and the Synology NAS. I haven't done any hard-testing on the equipment yet but after some minor upload tasks it seems as if the speed increases somewhat at least.
I'm not sure if my Synology DS210j supports Gigabit networking, but would it gain the network speed if I replaced my Dlink Dir-635 with a new router, e.g. Dir-655?
Also I'm not sure if the network card (802.11b/g/n) could be another weak spot in my network. What do you think?
Thanks!

If you have everything connected to the switch, i.e. PC and NAS, speeds should be very good, however other things could interfere with speed, yes, your NAS if it's not supporting Gb connections, If your using wireless, then that will effect transfers, specially if you can't get N modes.
I do recommend wired if your needing connectivity with the NAS. Wireless at best will see 8-maybe 15Mb per sec at the highest and thats just the nature of WiFi. I have my MacBook Pro set up on 5Ghz N only mode running thru a AP thats also set up for N mode at 5Ghz and at best I see maybe 10Mb sending files to my wired server on a Gb connection. Wireless is just funny this way, the connections are different and speeds are different when using wireless. If your trying to run wireless thru the router and connect to the NAS, I might presume that the router regardless of any router you use might be the bottle neck and thats just how routers work, there job is to route data and thus can impose speed performance slowdowns. Why it's best to run wired if you have high traffic or streaming large items from servers or NAS. It's just hard to push large data chunks thru the air waves.
You can try setting the router to Single N mode and see how it goes. You'll need to make sure your wireless card can support single modes. Most of them do now days. Test with security OFF then test with using AES a only if your wireless card supports it. Also test with your PC wired to the switch and send and copy files from the NAS. I bet you'll see upwards of 50Mb on wired. I do.
Keep us posted.

I'm having trouble finding the settings for N - I simply don't know where to find it (in the routers web interface).
I have a realtek RTL8191SE card supporting 802.11b/g/n in my Toshiba laptop.
The Internet wall socket is situated in the living room as is the entire setup (excluding PC) so unless using a Home Plug device I'm not sure if physically connecting the PC and NAS is an option.
I've tried to connect the PC and NAS using a cat5e 1 meter cable, both directly and through the switch. The transmission speed when transferring a .flv file of 23 MB was around 3 mb/s through the switch and ~4 mb/s when connecting the PC straight to the NAS.
-
Wireless settings are under Setup/Wireless/Manual.
-
Thanks!
Ok, so I'm currently running 802.11n only and AES only. Can't see any noticeable difference in speed though, around 1-2,5 mb/s.
-
ya, could be your Wireless adapter could be a bottle neck too.
Any security SW running on the PC while your transferring files?
How far away are you from the 635?
Turn off Short GI and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.
Does turning off WMM enable have any effect ON or OFF?
-
Hi!
I'm running Zone Alarm Free and AVG Free on my PC. My PC is around 8 meters (~25 ft.) away from the router.
If I turn off Short GI and Extra Wireless Protection and WMM enable "all associated wireless clients will get disconnected". Does this (only) mean that I will have to log these clients back on to the network? (daft question perhaps :) )
-
Can you test with a bit closer?
Yes you'll get disconnected only because you are changing the WiFi configuration and the router has to quickly turn off the wifi and make changes then back on. Happens on all routers.
-
Hi,
I turned off Short GI, Extra wireless protection and WMM enable. Then I tried to copy 2 the same 23 MB .flv files from my nas to the PC averaging under 200 Kb/sec...
-
Reenable WMM Enable...
-
Hi!
I reenabled WMM and speed increased to ~2 mb/s.
I have a cat5e network cable between the modem and the router, would replacing this cable with a cat6 have any positive effect on speeds?
Also I'm thinking of placing the Router on the top of a 2,10 meter cabinet to improve the signal, although this means cables that are around 4-5 meters will be needed.
Any experience with "home plug" devices? While I have only heard of them, some people say that their performance depends on the existing electrical wiring i the house. If these work I could actually connect the NAS straight to the wall socket (through such a device) and to the PC.
-
Possible that CAT 6 might have some impact however nothing that would greatly improve the speeds. Your just dealing with trying to get data going thru the wireless and back thru the router to the NAS. I would recommend you go wired CAT6 from the PC thru the switch to the NAS and by pass wireless when you need NAS. It's possible that you might to try a DAP wireless device if you really want wireless and connect it up to the switch with the NAS. This might improve the signal for wifi while still leaving the main host router as your internet gateway. Might try a different wireless adapter card as well. If you really want to use wifi and NAS, you might try 5Ghz. However not all devices support 5Ghz.
I have 2 routers set up as APs one in the office and one in the living room. Mine run 5Ghz N only for my MacBook Pro. Again, I only see about 8-10Mbs on uploading to my server. We'll never see greater speeds unless the Mfrs do something to increase the data thru-put. Just alot of variables to deal with when working with WiFi.
I've only has some experience using power line adapters, they seem pretty good and ya, depends on how well the power cabing in the building is done. I don't prefer this however only in extreme cases where WiFi might not work well.
Keep us posted.

Really sorry to bother you with all these questions: :-[
A DAP? Is that some sort of Access Point?
”Might try a different wireless adapter card as well. ”
My current wireless card supports 802.11b/g/n. All the specs and standards makes me really confused:
How can I tell if a wireless card has Gigabit support? Does it say ”802.11n Gigabit”?
”If you really want to use wifi and NAS, you might try 5Ghz. However not all devices support 5Ghz.”
I'm not sure if any of my appliances supports 5 GHz, and to be honest I don’t know where to find out, although I believe I saw "2,4 GHz" at some point in D-link web interface yesterday…
”I've only has some experience using power line adapters…”
If I moved the NAS into the next room (where I keep my laptop), I would have to connect it to my network either using a Powerline adapter or a wireless dongle, unless pulling a 20-30 meter long cable along the wall and ceiling.

In the specs list for my Synology DS210j, under Hardware it says ”LAN: Gigabit X1”. Any idea of what this means, anything to do with Gigabit Ethernet?

My current wireless card supports 802.11b/g/n. All the specs and standards makes me really confused:
How can I tell if a wireless card has Gigabit support? Does it say ”802.11n Gigabit”? No, WiFi currently has not hit the Gb connection speed nor will it for a long time. All wireless speeds are Mb or Megabits.
”If you really want to use wifi and NAS, you might try 5Ghz. However not all devices support 5Ghz.”
I'm not sure if any of my appliances supports 5 GHz, and to be honest I don’t know where to find out, although I believe I saw "2,4 GHz" at some point in D-link web interface yesterday…Contact the Mfr's of the devices you have and ask. Specs will show what is supported. If you don't see 5Ghz listed anywhere then it's probably not supported.

Any chance of this happening? I would be preferred to have the NAS and your PC connected to the switch, then have the router connect to switch as well for internet. I think this router isn't Gb supporting on the LAN ports in back, only 100Mb speed. The Gb Switch will get you GB speeds on wired.

How long have you had this router?
-
Hi!
I've had this router for a year and a half or so.

Well, maybe. Let's pretend that I move the NAS, switch and router to the adjacent room; then a dongle or a Power line/Home Plug is not an option I asume, and I would have to pull a network cable from the living room to optimise speed, right?
My blu-ray player and Sonos ZP90 media player is also wired to the router. The ZP90 is hooked up to my home stereo amplifier as well (I'm streaming music mainly from NAS via the ZP90 to the Hifi system).
Pulling the network cable around the wall and over the threshold is the most convenient way (since the inner walls are 20 cm thick and made of concrete), provided that bending the cable in several directions around corners and tresholds doesn't affect the cable performance.
Perhaps a flat network cable would do the trick or are they more fragile?
---
Would you say placing the router on top of a 210 cm high cabinet would improve the LAN speed noticeably compared to having it stuffed inside a TV bench? (We have such a cabinet next to the TV bench, that's why I'm asking)
-
I don't think they make flat style LAN cables however they are flexible enough if you don't constantly bend them. I have one LAN cable going from my back officer where everything is, around to the office door, around the corner and up the side door well to the ceiling in the hall way where 2 other doors meet, over in the head way and back down to the hallway and runs down the floor board in the hall way to the living room, up and down the door way entrance to where a switch and 2 APs are located. Of the switch is a wired xbox and Boxee Boxx an the 2 APs. Placement of the router doesn't effect LAN performance, only wireless and cable management and lengths.

Ok. Here's an example (ca 33 USD/21 pounds sterling) although it's only cat5e:

Link is bad.
I recommend CAT6 though if you can get it

OK, here's another link (hope it works) http://www.kjell.com/sortiment/dator-kringutrustning/natverk/tradburet-natverk/natverkskablar/fardig-langd/utp-flat-cat5e-vit-20-m-p68072
It's almost half past eleven pm here so I need to go bed. I'll dig deeper into this tomorrow and will keep you posted in this matter.
Thanks for all your input so far and have a good day :)
