What steps will reproduce the problem?
1. Connect Huawei E3251 DC HSPA+ USB Modem
2. Configure incl. modeswitch ans so on
3. Connect

What is the expected output? What do you see instead?
Expected is an DC-HSPA+ (dualchannel) connection with up to 42 Mbps (about 22 
Mbps at my place - testet with notebook directly).
But there is only an HSPA connection (one channel only) with about 7.5 Mbps.

What version of the product are you using?
WL500gx-1.9.2.7-d-r2624.trx 

Please provide any additional information below.

Thank´s for your fast response.
Do you know if any other DC-HSPA+ modem is working?
I will have a look at the resources in the evening.

You can find list of modems tested by customers in /usr/share/modems.conf
Most of reports posted at wl500g.info forum.

First of all, old routers has very limited USB speed.
At second, your modem may have special initialization sequence to init 
dualchannel mode.
